[Crossover] A Baby-Faced Spring

I'm Ryugamine Mikado.

My biggest dream is to build a society where the extraordinary can be observed at any time.

I thought that dream was hopelessly out of reach. But after my partner chose me to take part in the battle for the throne among one hundred demons,

I realized that there were so many extraordinary phenomena all around me.

Like an invincible esper, a baby assassin who can shoot a gun, and the dragon of Yokohama.

I feel like my dream is about to come true.

And I'm absolutely delighted.

Guide:

A mountain of headcanons and OOC. This isn't a canon-accurate boss.

I've written myself into a hole, too.

So just read it for fun.

Theme: The boss is diligently pursuing the extraordinary again today.
