Once upon a time, there was an honor student who [[TheEndOfTheWorldAsWeKnowIt blew up the entire universe, along with some neighboring ones]].
A few billion years later, he's approached by [[Anime/PuellaMagiMadokaMagica Hope herself]] with an offer: save the universe he destroyed. He accepts, and gets sent off to [[Manga/MahouSenseiNegima Mahora Academy]], just a week or so before a very fateful trip to Kyoto.
And from there, an adventure begins.
A (soon-to-be) MegaCrossover focusing mainly on ''VideoGame/Disgaea3AbsenceOfJustice'' and ''Manga/MahouSenseiNegima'' with cameos from other series written by @/LoveIsWeird, [[http://www.fanfiction.net/s/7212267/1/Disgaea_Presence_of_Hope Disgaea: Presence of Hope]] takes place after [[AlternateEnding the Human World ending]], aka [[SuicidalCosmicTemperTantrum the one where he blows up the universe]], and tells the story of what happens when you stick a MadScientist from ''Creator/NipponIchi'' into Negima.
Please add tropes as you see them!
* LaserGuidedAmnesia: Mao gets this done to him, but is slowly starting to remember.
* ReincarnationRomance: May be happening between [[spoiler:Setsuna and Konoka]], though the author is trying to keep mum about exactly who they are. Not that it works.
