Come Out, My Valkyries

Fandom + multi-dimensional travel There are thousands of ways to travel through time, but Gawain dares to say that his start to time travel is absolutely unprecedented! He complained that life was too boring, so he was time-traveled by a passing master, who also gave him a cheat system, which allowed him to draw character cards. Which character card he drew could summon which character, and he could also enter the world where that character came from to have a big adventure. "This time, I must give SSR!" ——This is a story about summoning girls, going to their world to help them fulfill their wishes, and causing trouble along the way.
