Ichiro Tachibana is the firstborn, golden son of Hiroto and Mayumi Tachibana and elder brother to Jiro “Jaxon” Tachibana. To their parents, Ichiro was the perfect son: a successful and wealthy doctor with a happy marriage and children, living in a suburban home with a white picket fence. He seemed to be living the dream, but that wasn’t the reality.

The reality of Ichiro is a mad scientist who engineered a bio weapon that turns people into ghastly monsters dubbed as “Richonoids” to play god and torment his brother, Jiro. Behind the walls of that suburban white picket fence home is a room dedicated as a shrine to Celeste Marcella, Jaxon’s girlfriend and object of Ichiro’s affection. His wife and kids were nothing more than hired actors to ward off an arranged marriage to Noriko Nakamura.

His father, Hiroto, greatly overestimates his relationship with his son and underestimates his power. He often relies on Ichiro to clean up his messes for him like a child, wearing on his patience.

Percy Pearson did the unforgivable when he released a video of Ichiro being tickled for the world to see. Ichiro is hellbent on destroying and killing Percy for that slight and will go to great lengths only to fail in his pursuit, as Percy is not your regular person. Ichiro also has his targets set on destroying Tristan Trémaux, due to his involvement with his brother, Jiro, and exposing Ichiro for the monster he is to the world.

It seemed Ichiro finally met his match in Robin Renard, the owner of Foxy Robin’s nightclub and Percy Pearson’s ex-girlfriend, as she shared Ichiro’s wicked ways and embraced them. But she wasn’t Celeste, and Ichiro soon grew tired of her. But Robin had other plans. He wasn’t going to get away from her that easily.
