Disgaea Presence of Hope

Once upon a time, there was an honor student who blew up the entire universe, along with some neighboring ones.

A few billion years later, he's approached by Hope herself with an offer: save the universe he destroyed. He accepts, and gets sent off to Mahora Academy, just a week or so before a very fateful trip to Kyoto.

And from there, an adventure begins.

A (soon-to-be) Mega Crossover focusing mainly on Disgaea 3: Absence of Justice and Mahou Sensei Negima with cameos from other series written by User:Love Is Weird, Disgaea: Presence of Hope takes place after the Human World ending, aka the one where he blows up the universe, and tells the story of what happens when you stick a Mad Scientist from Nippon Ichi into Negima.

Please add tropes as you see them!


 * Laser-Guided Amnesia: Mao gets this done to him, but is slowly starting to remember.
 * Reincarnation Romance: May be happening between, though the author is trying to keep mum about exactly who they are. Not that it works.
