Missing details aside, I like the anime more. MC isn’t in the dirt humble and the party is a little more smart for rookies. The unreasonable amount discrimination isn’t there so Thunder Pike looks even dumber.
It seems they wanted to make it a thing for this comic, despite the novel making the human form just something to separate away from the princess training, at least as far as I read.
Maybe the hair healed? Sounds like they might of tried healing with elixirs, but it wasn’t strong enough to heal it all or it would take most/all of it to heal her.
Kyuu: I learned how to make an energy sword!
Win: I too learned how to make an energy “sword”!
Kinda wish she stayed small so the energy dick would be more comical.
