Inuyashiki - Last Hero

Ichiro Inuyashiki, a worker whose life is pretty uneventful, has a very ungrateful family, despite having built them a house.

Reborn a robot, Inuyashiki finds meaning by saving others; meanwhile, high school student Hiro Shishigami has also been reborn a robot, but has no regard for anyone.

Shishigami is shocked to see Inuyashiki stand up from a blow that should have killed him then fly away; seeing that, Inuyashiki knows that Shishigami has a robot body just like himself.

When the fully tattooed yakuza criminal Samejima finds a girl he likes, he kidnaps them, drugs them up, and then roughs them up; Fumino was happy; she had a job and a fiancée.

Ando is struggling with the fact that his friend Shishigami is responsible for the spree of home invasions that have occurred recently.

Shishigami escaped from a dozen officers, but he has become a wanted man in connection to the home invasion spree; he stays with Shion Watanabe, a classmate.
