DESCRIPTION
These guys are Seiichirou and Aresh from "The Other World's Books Depend on the Bean Counter".
In episode 1 Seiichirou overdoses on magic potions and in episode 2 it is discovered that his body has intolerance to magicules (kind of like molecules but magic) also he is severly unerweight and pretty much anemic since he barely eats anything at all.
The Commander decides to help him by making sure he eats well every day since foods also have magicules in them, thus building his tolerance.
All that is canon so I kind of wanted to expand on this treatment... 👀 I think the Commander is liking the results and wouldn't mind if Seiichirou became a little softer.
