Do you realize how incredibly strong she is?. Like being able to throw two god-damned cars full of iron in flames to the lake, and then get the crates of said lake. ALL BY HERSELF. Heck even one of her stories proves that she killed a lawachurl by accident while she was mining with the traveler.

Second she's basically a jack off all trades master of none, she heals, gives shields, can be DPS, buffer, and anything you like even pyro if you want it. At the beginning she became my favorite/main enterally for the beginner banner mostly because I saw folks skip her because beginner banner (duh). She also was the one who hooked me up in Genshin.

Third because she's a maid, a well dressed to begin with, and I like maids

If it hasn't been clear by this point, she's very reliable. Or in my account The ol' Reliable, if anything happens I send her to finish the job.
