When he is not scared, whining or crying he has show to be eager to race the adults or to be reunited with his grandmother. As a typical kid he is very obsessed with himself and his own emotions, not yet having developed the skills to deal with difficult circumstances as the one he finds himself in.

Tanaka Alien Mission Arc

He is first seen in the car with his grandmother being handed her phone with his mother on the other end of the line whom he tells he had a great time with his grandmother right before a sleepy truck driver runs his truck through and over them killing both them and Masanobu Hojo and Sadayo Suzumura on the motorcycle in front of them.

Arriving in the Tokyo room they wonder what's going on with him crying he wants to go home. Kato then explains what is going on regardless of Nishi's anger. After the sphere in the room opens revealing suits and weapons he and his grandmother confusingly look at them, with his grandmother asking Kato where they are with him answering they should put on the suits saying it will increase their chances of going home. They listen to him and put on the suits. They then watch how Kosuke Nakajima shoots his rifle at Nishi only to have his head blown up by him, which scares him, seeking comfort with his grandmother. Who then gets send out of the room after Nishi and Kei Kurono, at which point he runs for comfort between Kei Kishimoto's tits. He then is the second to last to be transported out of the room leaving Kishimoto's bosom behind to reunite on the outside with his grandmother.

He and his grandmother then bear witness to Nishi shooting one of the Tanaka Alien Hatchlings which gets him in a fight with the Shopping Tanaka Alien. His grandmother then keeps him tight to her, thereby blinding him from the fight. Then as they see the bikers and the other new people leave they follow, as the ringing gets louder, he starts running towards the game line which engages the bikers to follow suit running after him, with Shinsuke Nishikawa overtaking him just to have his head explode thanks to the bomb inside of it, making him run back to his grandmother for comfort. They then go back to where now Kato is fighting the alien, and he is shielded from the action by his grandmother again until it is defeated and they make their way down the stairs to join Kato and the others. He then watches Nishi die and he starts screaming and crying because he doesn't want to die, which causes the remaining two bikers to treating to kill them at which point Kato exclaims that if they want to be free they should listen to what he has to say. Which they do choosing to follow Kato along with the others, while the bikers double back to a left behind Kurono.

As a five men strong Flock of Tanaka's attack Kato, he and his grandmother cower in fear and then run away into a nearby open garage at which point he tells his grandmother he needs to pee, he then takes of his suit showing his naked body while peeing against the wall, right when he is done two of the Tanaka's show up, he then runs to his grandmother who tells him to run away and that she is going to beat them up, he runs away still naked and hears how his grandmother is being killed without doing anything, a policeman then cycles by but seemingly ignores his pleas for help. He then runs back to his near death grandmother who hugs him as they both are killed by the Tanaka's. Only to be discovered moments later by the others.

Anime/Manga Differences

  • In the anime he is seen staying at his Grandmother's house for the weekend. His Grandmother tells him they will go shopping for toys the next day much to Ryota's excitement. The next day they are at the train station, Ryota impatiently presses the wrong button to receive a ticket for the wrong train, this annoys the other patrons at the station.
  • In the anime many of his scenes during the mission are abbreviated while two are left out.
