[Armor Otome] The Spirit Realm and the Nestling

If you toss a pebble into a calm, orderly life, the result is obvious: just as everyone in the Ming Realm was peacefully protecting the universe, Xiao Xi came crashing in like a nuclear bomb, flung there by fate.

A creature taken in by the group, she brought everyone plenty of fun and trouble. But sooner or later, everyone would realize that this was what family was like.

Still, some people would eventually realize that what they felt for Xiao Xi had never been familial affection in the first place.

Content warnings:

1. Adoptive father-daughter dynamic, not the Emperor
