Also Belial. How could I forget Belial.

And, depending on the ship and purposes? Vore/cannibalism.
((Look at Hannibal, Ren, Mulder, Shimei and Mo Ran)) you all made it possible.

somno! I think since most of my ships have as a basis pure trust and loyalty, the very thing of delivering themselves to the other makes me go 👀👌✨

I would say... pick Ga Ming as a free 4star and with lots of effort you can get a decent pyro dps.
It will be hard BUT it will allow you to safely pull for Wriothesley.
