I don't usually post sketches by themselves but I still like this concept.
This is a little doodle that I was gonna make into a mini comic.
Wally has a giant computer were they save their memory and deals with Lacrimosa's security. They always do it each night in case their body is
destroyed/compromised in battle, their ghost form is very forgetful.

Additionally they dislike to be seen without their "skin" (shield) and only allows Ally to be/sleep in their room.
