I looked into the anniversary encyclopedia because I got impatient and a very cool person using a very cool name uploaded them and a ton of other guides
(*´艸`) They call Stahn's hair 見事. Rays also says his hair is in surprisingly good health and really nice to touch and beautiful and 立派. They gotta start drawing his hair more like the Asteria art where it's all fabulous 'cause it usually looks like neglected straw to me lmao
Really... this depiction of his hair is far more worthy of most of the praise it gets. But I think it's also the only time it's ever been like this. Some of Kasukabe's art has him with kinda uncanny looking hair sometimes but I guess it looks softer than the usual depiction.
Yeah, the Asteria art is probably the go-to if they want to visually convey his hair is "nice" without compromising on the wild shape too much.
...Ah, anyway...
The first note on Leon is also ( .;´;_ゝ;｀:,) But I don't think I understand the very first part of it well enough. Something like "Thinks the lowest of others more than anyone else, but is also wishing for love more than anyone else." It has a better flow in Japanese but I don't know how to grammar my English to work as well. His second page feels like it's retconning some stuff even from DC? I'll patiently wait now for better people to translate it, but something I think I read on it specified that he wishes for Marian's happiness above all else, which... I would sooner write (not translate) as "wellbeing" since that's pretty dang incorrect since she explicitly does not want him to be doing the things he does for her and he should damn well know it won't make her happy.
