Tatsuka Rikka. That is my name. Some time ago, I landed in an alternate DxD world and found out I have a Mystic Eyes that lets me analyze every spell that I sees and a replenishable Command Spell that allows me to transform into Servants, to which they're the ones in control of. Oh, did I mention the transformations are based on a num gen? (No harem or pairing for MC) [Also on Ao3]

Sequel to "It's Always Sunny In Trifas", the Fate/Apocrypha Dual SI featuring myself and Lord Trent Blackmore. Read that first! That said, this will be a Highschool DxD/Fate crossover, with the bulk of the crossover being DxD. Be ready for big dumb shonen shit and big dumb anime tiddy, because that's this setting in a shellnut.

Rias Gremory, desperately in need of a helping hand to save her future summons a legendary hero from human mythology. Some call him The Child Of Light. Others call him The Hound Of Chulainn.

Did Shirou have a clue what was going on? No. Not really. But that was nothing new. In fact, all of it seemed oddly familiar. Everything was the same, from the hole in his chest, to the black haired girl with a glow red object. Now he was involved in a war that previously had nothing to do with him, with the fate of the world hanging in the balance. So you know, same old same old.
