Undertale Vs Honkai Impact

The lazy author appears, and the newcomer's first article... I understand everything. There may be some AUs and some secondary creations of AUs. Of course, the beginning will be a little boring. I hope you can support me. This work is a piece of writing that I made when I was free to use my imagination. If there are some AU settings that you don't know about, go and search them. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
