AIKa Wiki

Reiko and Manami are members of the White Knights. They are not ranked as highly as Kana Shiraishi or Rin Shiragiku who appear to have the same rank as fellow White Knight Misumi.

Both girls are members of the school swim team with Kobayashi as its captain who holds a grudge against her fellow team member named Misumi. After they were probed by Alien Tendrils by Miyu and E.T.A.I. due to their strength. Manami is Reiko's lackey and follows her lead. They were seen trying to defend Miyu Shiratori from being captured.


Reiko has fairly spiky reddish-brown hair tied in a ponytail off to the side of her head, while Manami has light brown hair which reaches a little past her shoulders. Both girls wear the white dress that the White Knights wear, although Reiko wears green sweatbands on her wrists and brown knee-high boots while Manami wears white knee-high socks and loafers. Both are beautiful yet arrogant.



Reiko and Manami are first seen at the end of episode 1 with fellow white knights Yui and Misaki draped over their shoulders as they were defeated by Aika earlier.

E.T.A.I then knocks both of them out with her tendrils and has Rin and Kana carry them over to a couch

Near the end of Episode 2, Reiko and Manami fight Aika Sumeragi in the underground base beneath the chapel. In this occasion they show they have good coordination and fighting skills, but are still both eventually defeated.

Initially the couple could not only hold their ground against Aika, but even disarm and land land a few hits on her. However, when they grew confident and tried to finish her off, the far more experienced fighter turned the tide on them.

At one point in battle, Manami manages to pin down Aika by grabbing her from the back. Seeing the opportunity, Reiko rushes to attack the inmobilized salvager from the front. She takes too long, however, and before she is able to reach the girls Aika manages to free herself by stepping on Manami's right foot, causing the White Knight to get distracted and lose her grip on her. Aika then grabs Manami's head and uses it to help herself jumping on the air, positioning her whole body horizontally with both legs wide spread just as an already too late Reiko comes barging in. In this way the arriving girl's head ends up just between the salvager thighs, where Aika then hastily traps it with a pincer movement as the White Knight can only stare in disbelief. Before any of the two girls can actually realize the full extent of what's happening, Aika follows with a brutal flip, which send them crashing against the floor on opposite directions.

The move leaves both girls dazzled and confused, and Aika quickly moves to make the best of the situation. The unlucky first pick ends up being Manami, who lies head and chest against the floor, totally defenseless, with her butt raised and eyes closed, still struggling to recover from the blow. The poor girl doesn't even have time to realize what's happening before Aika lands a demolishing chop to the back of her neck, which sends her gasping for air as she screams and falls humbled and unconscious.

The time used to humiliate Manami, however, is enough to allow Reiko to recover and get back into the fight. Still clearly affected by the blow, the remaining girl decides to charge Aika once more in a last attempt to win the fight. She is too slow again, though, and Aika easily dodges her hit, grabbing her by the waist in the process. In total control of the situation, Aika then unceremoniously turns the helpless girl upside down and, as she can only stare in shock, uses a demolishing piledriver on her, sending her head crashing against the floor. Already soundly beaten, Reiko still struggles against unconsciousness for some seconds, her legs trembling as she fights off the inevitable. It's obviously not enough, though, and finally she succumsbs, her legs crumbling over Aika's shoulders as she goes out of comission with a loud moan, her ass ending up directly in front of Aika 's face.

It is only now that Aika, who had kept a firm grip on the girl at all times while she shaked in an attempt to stay conscious, finally relaxes and lets go of Reiko, as she feels the White Knight go limp for good in her arms. Reiko's body then slumps slightly forward, since the Salvager is no longer pressing it against her own, and Aika thus finds her face no longer buried in her defeated enemy's crotch. Tired from the fight, she takes a deep breath as she relaxes for a bit.

With both girls finished, Aika then proceeds to recover her gun and continue pushing deeper into the base. She leaves the two White Knights lying unconscious on the floor, Reiko face down and Manami resting on her side, skirts hiked up and asses exposed. Maybe as a sign of respect for her defeated enemies, she gives their unconscious bodies a silent and pityful last look before moving on.

Both girls are later seen draped unconscious, humiliated and humbled over the metal slab. Here we are given a great view of Reiko's ass, which due to the position of her body appears to be especially sticking out. It also seems evident Manami has the biggest hip of all the girls, maybe only rivaled by Kana Shiraishi. Both girls have their skirts hiked up all the way to the waist and beyond and lines of drool fall from their mouths. Their possible fate is that both girls got into custody and even interrogated by some agents or military, The fact that Karma will be hitting hard on the two poor girls.


  • The names Reiko and Manami means:
    • For the name Reiko, it mean "thankfulness" (rei) and "child" (子) (ko), which means "child of thankfulness".
      • It can also mean "bell" (鈴), "beautiful, lovely" (麗) or "the tinkling of jade" (玲) (rei) and "child" (子) (ko).  
      • Part of the name Rei is also part of the Bushido or way of the warrior. The Bushido was basically the Samurai code of honor and "Rei" is translated to "respect".   
    • For the name Manami, it means "love, affection" (愛) (mana) and "beautiful" (美) or "sea, ocean" (海) (mi).
    • Similar to how Yui carried a red haired girl over her right shoulder and then Reiko carried Yui over her right shoulder, Rin carried Reiko over her right shoulder but was standing on the left as opposed to right

Aika R-16 Paralellism

Reiko is finished off in a very similar way to the last averagely sized Karen clone from Aika R-16's third episode, Deep Blue Girl. Both enemies are beaten by Aika using a piledriver on them, and their ending sequences are fairly similar. The two poor girls have their heads crashed against the floor rather unmercilessly, and after this struggle for some minutes to remain conscious while their legs tremble, all the while Aika firmly holds them to make sure they end up out for good. Eventually, they both succumb in her arms, and their outstreched legs crumble, after which the Salvager relaxes her grip and takes a good breath before moving on.

Differences bettween both scenes include that the piledrivers are with the girls facing opposite directions. Reiko is facing Aika, in a way that each of their faces end up buried on the other girl's crotch. Also, this causes Reiko's legs to crumble on top of Aika, and so the Salvager must throw aside her body before getting up, which is the origin of the sound we hear inmediately adterwards, before she retrieves her gun. It also explains why her body is moved when we see it again.

On the contrary, the Karen clone is facing away from Aika. This gives us a view of her breasts as she comes crashing down, since her skimpy top falls all the way to the gound and leaves her totally exposed. It also means Aika's face ends up in front of her ass, as opossed to her crotch, and that her legs crumble freely and not on top of the Salvager. This is why Aika has no need to move her to get up, and we always see her on the same position afterwards.

Additionally, both scenes are excellent to illustrate Aika's progress throughout the series. When she brings down the clone, she does it in a rather unprofessional manner, screaming and being deeply agitated afterwards. On the contrary, when she performs the same move on Reiko, she always seems to be in total control, moving swiftly and taking her down in a brilliant single manoeuvre.

This is consistent with most Aika R-16 knock outs, which in several ways seem to be overkills most of the time, since Aika can't really control her strength very well and overdoes things in multiple occassions. She also tends to panic and thus goes overboard when trying to bring down her foes. For example, Midori and Aki are two untrained teenagers, but since they are armed and catch they young Aika off guard, she is too scared to try to go easy on them. Aki gets not only a brutal knee to her stomach, which probably would have been more than enough to take her out, but afterwards also an elbow right to her spine, in a devastating pincer movement which almost everyone would find way over the top. Midori had a similar fate, being shot two times out of desperation in the brink of the moment, when 1 shot could have easily taken the girl down for good. This is in sharp contrast to Aika Zero, in which Aika's strikes are much more measured and chirurgical. A good example is the Drama club fight, in which Aika one shots all her foes with ease, landing precise blows to their open weak spots, never using more strength than precisely required.

This ends up being rather obvious in the aforementioned scenes. Aika brings down Reiko in a harsh manner, but with no excess force. The piledriver is clean, and the girl hits the floor at 90 degrees, the whole impact being absorved by the top of her head, the skull firmly clutched between Aika's legs to prevent neck movement and unnecessary damage to the spine. Aika always has her feet on the ground and she just brings Reiko down as she herself performs a downwards movement, thus controlling the strength applied.

On the other hand, the Karen clone is not even nearly so lucky, due to Aika's lack of expertise at the time. Aika seems to just grab a hold of her as best she can, and pays no attention to details in her attempt to just finish the girl off. With the defenseless clone firmly clenched in her arms, she just jumps upwards and then plummets down, seeking to simply take out the clone by making her hit the ground head first. She has no measure or control over the amount of force used, giving herself totally to gravity as she falls downwards. However, in the sloppy position adopted, the girl is far too below her and her head hangs freely, with nothing to encase it as it hits the ground. Thus, the overkill is all set to happen. The clone does hit the ground head first, but since she has it slightly tilted backwards as she screams in fear, the impact hits her square in the face. This causes her neck to bend further back, and the whole head turns backwards instead of to the front, as it should ideally be in this case. As uncomfortable as it might be to the girl in question, it must be said that the position does allow us a clean and unobstructed vision of her breasts as they bounce and jiggle in response to the impact.

However, the affair is not yet over, as Aika is yet to touch the ground. Sadly, as the clone is facing the same direction as her, the head turned backwards means that the poor girl has found her head precisely below the plumetting Salvager. Their bodies being strongly pressed against one another, it means that, even if we do not get to see it, there is only one way for things to turn out. As the clone is lying on the ground pretty much done for, Aika's butt has no other option but to land right on top of the back of her neck, further increasing the pressure on the spine, now unmercilessly trapped between the hard floor and the whole weight of the Salvager. The normal thing in this cases would be for the body to naturally straighten itself up, by collapsing downwards and hitting the floor, releasing the tension caused by the nearly unthinkable position. However, since Aika still has the clone firmly grabbed by the waist, this is impossible, and as the Salvager continues to strongly clutch the shaking girl out of fear she might get up, she further racks up pressure to the neck's vertebrae. Thus, the sloppy piledriver ends up being more of a weird chokehold, the poor girl subjected to probably the most brutal knockout in the whole series. Her sad moans as she trembles in shock, still firmly grabbed by Aika, can then come as no surprise. Luckily for her, she does not hold up much longer, and finally succumbs. As the tense Salvager finally feels her go limp in her arms, she at last lets go of her, and thus puts an end to the whole ordeal, one of her sloppiest, though still thoroughly enjoyable, KOs.

Agent Aika Paralellism

The Reiko and Manami fight also bears a slight resemblance to the altercation with the Delmo Commander and the Adjutant in Trial 6 of the original Agent Aika series. In both cases, Aika faces two highly skilled foes who work together and fight as one, proving to be quite a challenge to overcome. However, Aika is able to beat them in the end through her superior fighting techniques and expertise, finding a way to break the girls partnership at some point and then taking care of each of them at a time.

In Trail 6, a grown up and more proficient Aika, is able to do this when she sees her foes repeting an attack pattern they had already used, which enables her to respond with a brillaint counter of her own. The surprise movement by a just seconds before seemingly defeated Aika takes both Delmos by surprise and the girls can do nothing but watch as Aika lands two mid-air demolishing kicks to their foreheads with the back of her heels. Both girls thus end up plummeting to the ground confused and apart from one another, and Aika takes quick advantage of this situation to finish each of them separately.

In Aika Zero, the execution is less precise, but the core idea still remains. This time, a younger and less experienced Aika finds herself pinned down, and is forced to resort to the cheap tactic of stepping on Manami's feet to gain upper hand. However, once this is done, the rest of the fight follows the same pattern. The freed Aika manages to get a hold on both girls at the same time and then sends them crashing simultaneously to the floor. This once again leaves both enemies far away from each other and dazzled. The Salvager then swiflty takes care of each at a time before they can rejoin their forces.
