Sent to an alternate DxD world with a Mystic Eyes and Servant-trix by TheRed0One1

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?
