Anime Crossover: I Have Determination, So Don’t Try to Win Me Over

[Some Characters Switch Gender, Male Characters with Female Appearances, Multiple Female Leads]

What would you do if one day you gained the power of Determination from Undertale?

Then you found out you weren't actually from this world. What would you do?

Answer: Save the world.

But why does my Determination seem a little unusual?

We know that every human in Undertale has a different kind of Determination, so why am I surrounded by so many bad women, huh?!... ヾ(;ﾟ;Д;ﾟ;)ﾉﾞ

And so, in order to save the world and strengthen my Determination, I am forced into conquest.

A quick introduction to the protagonist's abilities: they're similar to those of a succubus. I won't go into them here. A heads-up about Undertale: it's mainly because that stuff is too complicated. The protagonist is a cute guy who grew up in human society, and of course there won't be any BL here. The main reason is that the author is a guy, and it's fine to read this kind of thing now and then, but actually writing it myself would feel pretty gross.

Also, having the power of Determination from Undertale doesn't mean the story will actually include Undertale content. Those things might appear in his memories, but they won't happen in reality.

The protagonist's second ability is something like simulation. That's all.

The cover is AI-generated, but the author isn't AI. Updates might get a little slow later on, since the author is still a student.
