Dean Mori Doesn't Want to Work Overtime

In this IF timeline, Mori Ogai, the former leader of the Port Mafia, learns about the "Book" from the current leader, Dazai Osamu, against his will.

All he wants is to take good care of the orphanage and leave Yokohama in the hands of the "diamonds that will polish themselves," but all sorts of inexplicable characters keep showing up: ninjas from another world, the Flame Rings of the Kings, the Vongola family, and more. All kinds of supernatural forces appear as well: yokai, vengeful spirits, curses, hollows, Soul Reapers...

The inexplicable characters do have one goal in common: to destroy the world.

So Mori, the orphanage director who doesn't want to work, is forced by fate to take the path of a magical girl... or, rather, saving the world through overtime.

Well, he might as well save the diamond, too.

PS: This is an IF version of Mori. Any differences from the original work should be treated as my own headcanon (bows deeply). This is a crossover with many worlds. It's focused on pure romance, but the pairing hasn't been decided.

PPS: To borrow a line from Nanami: "Work is XXX."
