Your comment somehow reminds me of that manga where the hero was just a tween girl, a messed up tween girl, and the Demon Lord ended up practically adopting her as his own daughter.
Ah I was thinking this is the guy who betrayed them in the past timeline but guess not since Tia didn't react.
I'm thinking she'll completely awaken once she sees the porter and remembers her trauma.
No, I was pretty sure from his first appearance that that’s who he is. They went through the trouble of blocking out the name and having him complain about only having one human face. Tia seems to think he was a coward who ran away rather than an actual enemy
