Ultraman: Collecting Monster Girls, Starting with Tiga

(No fanservice, no suggestive content) (Showa + Heisei + Reiwa, separate worlds, with a new Ultraman’s world in each later arc)

After transmigrating into the Ultraman world, Duanmu Feng accidentally obtains a magical Spark and becomes a monster girl collector, gathering all sorts of monster girls in his daily life.

Monsters on the rampage? No rush. Let Ultraman take the first hit. Once the battle’s over, I’ll collect them, then challenge him to a fight too. After all, my monster girls need to grow, and the Giants of Light make the best sparring partners!

Duanmu Feng only wanted to quietly build up his strength, but gradually he realizes that his monster girl legion seems powerful enough to go wherever it pleases. Why do all those aliens call me the Monster Emperor? I’m clearly a five-star citizen, for crying out loud!
