Mc won't need a wand

Mc will be reincarnated(probably with no knowlage from dxd world), they won't have imperio nor legimens, i will explain it by the fact that the spells mc has acess to beeing randomized once they got into the new world(mc would be quite lucky and have acess to nearly all spells he remembers from hp world)

Mc will have the room of requirements as a sacred gear, mc will be able to make a door to it apear in front of him whenever he wants, mc will have a magical herb garden and magical zoo in there so he can make potions, and a house elf to tend to them

Mc will be rainare's target(no issei here) and mc will use protego then stupefy on her when she trows the first light spear, mc will be then dragging her to the room of requirements, where he will bind her and interrogate her via veritaserum. After learning all he can, mc sobers her up from the veritaserum and proceeds to crucio her into insanity before avada kedavra-ing her because she f*cking deserved it after everything mc heard her say she and her friends tend to do to inocents(mc will also regret not having acess to a dementor that day). Mc will then storm into the abandoned church and rescue asia, leaving no survivors besides them 2

Mc will also have some form of phisical enhancement as one of his transmigrator cheats(so he can keep up with the supernatural's speed and stuff), i am leaning on supersoldier serum but i may change my mind

I won't make mc a devil, he will be on a contract with rias
