Ultra: I Actually Saw Ultraman

[Broken character design + female protagonist + multiple male protagonists + no system + heartthrob + demolishing CP + Ultra Otome] The new generation originally just went out to do tasks together, but they encountered a giant black hole halfway. The new generation were caught off guard and fell into it before they could even send out Ultra signatures. Finally, they collectively traveled to a world without Ultraman, and the location was actually a girl's home! (Challenge a new track, please quit if you think you are brainless, the author is a novice) [The private heroine later went to the world of the new generation, and also took the plasma spark tower and became Ultraman]
