In fact, thinking about it, it did seem a little absurd.
Just look at the enemies Ultraman usually dealt with: ancient monsters of Earth, attackers from other dimensions, overlords of the universe, interstellar bandits, higher-dimensional lifeforms.
You: a sixteen-year-old high school girl whose only special talent was liking monsters a bit more than most people, who could create monsters but none of them were all that strong, who was too weak to truss a chicken, and who usually could not even make her own meals.
Just thinking about how she was supposed to deal with a cheat who could power up through sheer will at any moment, and might even be able to call over a huge crowd of people to gang up on her, was already giving Akane Shinjo a headache.
Her, become an opponent of Ultraman? Seriously?
In fact, Akane Shinjo was not the only one dumbfounded.
Even the Mo Wangs in the group chat were dumbfounded right now.
[The Creation-Level System Administrator] has changed his nickname to [The Creation-Level System Administrator/The Benevolent Hero]
[The Slacker King of Hyperion]: Huh, what the hell? Group nicknames can change? Damn, this is the first time I've heard of something like this!
[The Blonde from Teyvat]: What what what? And it's a double nickname! This, this is basically heaven-defying, isn't it?!
[The Savior of Rationality]: So the group member wasn't Gridman, but was actually Cosmos?! Wh-what kind of plot twist is this? Where's Musashi?! No, what version of events is this supposed to be?
[The Video Store Owner]: Wait, according to what that group nickname means, the group member isn't just Gridman, he's even Cosmos too? Is something like that even possible?
[The Garbage King of a Certain Train]: Urgent urgent urgent, I just want to know what exactly happened now.
