Yuuta Hibiki

Оригінальне ім’я: 響裕太

Yuuta has amnesia at the beginning to the extent of not even remembering where he lives. He fuses with Junk to become Gridman. ~!It is later revealed that the Yuuta we have seen throughout the show has been Gridman inside of Yuuta's body the entire time, except he had forgotten who he was (explaining the amnesia).!~
