"Eri, when I am born again, I want to eat your rice ball... and be a part of your team. Thank you, Eri..."
―Ain-I of the Neutral's final words before his death[src]

Ain-I of the Neutral (ニュートラルのアインI Nyūtoraru no Ain Ai) is a starfish-themed Matroid of the Machine Onslaught Empire Matrintis.


Ain-I is a Matroid designed by Metal Alice in her own scheme to understand the concept of friendship so that the Matrintis would understand it and figure out means to defeat it as the Goseiger use it for themselves. During its first battle, she makes it seem like it is a worthless robot when she forces it to fight and take a Gosei Dynamic. However, Eri discovers that it isn't like a typical Matroid and decides to take it in, thinking that she can teach it to be a good being even with its evil origin.

Brought back to the Amachi institute, Ain-I is renamed "Koro" and learns many things under the guidance of Eri. However the other Goseiger, through their analysis, discover the Alice Bomb implanted on its body and realize that they have no choice but to remove it, even at the risk that Koro could die if it fails. During an initial attempt to remove the bomb, Eri diverts the Comprethunder card she was to use to destroy the bomb, thinking that it would kill him. However, Metal Alice reappears and deems the study a failure, upon which she activates the battle mode for Ain-I in order to defeat the Gosei Angels. Seeing the combo as the only way to bring it under control by attacking its AI chip instead of the bomb, the Goseiger prepare to try again with Alata now chosen to wield the Comprethunder card, but Gosei Pink decides to try again knowing that it is the only way to save him. With Eri completing the intended combination, they bring Koro back under control but, without his mind, reduced back to a doll-like state again.

With no other options, Metal Alice uses the Bibi Nails to grow Ain-I and use its Alice Bomb to destroy everything within its radius, now drastically increased with his size. While the Goseiger initially try Gosei Great to handle the Matroid, Eri decides to sneak off with Gosei Ultimate to fly Koro into the stratosphere in order to manage him herself. Ain-I's former memories reawaken and he decides to help the Goseiger dispose of him while thanking Eri for his love and the knowledge she granted to him. He is destroyed in his own self-destruction, with a memorial set up for him and Eri keeping his AI chip in memory.[1]

Initially, Ain-I appears to have no weapons, merely being a doll-like robot with an artificial intelligence chip within itself similar to other Matroids. However its true power reveals a more frightening face and a 150mm energy cannon on each of its' arms. It is also attached with an Alice Bomb (A(アリス)ボム Arisu Bomu) on its body with a 300 meter blast radius in his body.

Behind The Scene


Ain-I was voiced by Kappei Yamaguchi, who later moves on to voice as Ticket in Ressha Sentai ToQger.


Concept Art


  • Ain-I is named after A.I. Artificial Intelligence (A.I. Ē Ai).
    • He's also named after The Iron Giant (アイアン・ジャイアント Aian Jaianto), based on the concepts of the titular machine who learns from a boy to defy his programming to not be a mere war weapon and to be something better.
