Chou Jikuu Bakuren Monogatari ~Door☆Pi☆Chu~

Yoshitsune lives with his childhood friends, sisters Orihime and Otohime. Otohime likes delving in black magic and one day makes a drug that bend space and time. Yoshitsune ends up getting this power and summons lots of historical figures. However, he can’t make them return to their original time, so they end up living together with him.
