Bleach: Starting with Marrying Retsu Unohana

Araki transmigrated, but he wasn't panicked at all.
Because he brought with him character data from an open-world game based on the One Piece series that he played before he transmigrated.
Until Araki discovered that he hadn't transmigrated into a pirate world at all, but into the world of Death God...
Araki was furious about this!
Fortunately, in addition to the character data in the game, he also had cheats!
"What?! You can become stronger just by binding yourself with someone powerful?!"
"Understood, I'll go marry Retsu Unohana right now!"
Araki looked at his cheat system, and with his unconventional thinking, he immediately made a decision.
