If Rerir doesn't come back for the finale I might legit drop this fucking game for real.
I was legitimately so hyped for Rerir, loved his backstory, loved all this Khaenriah shit and for him to go out like that and not even be a villain just sucked all the fun for the rest of Nod-Krai.

I don't want another fucking Mary Sue Dottore moment I fucking hate that faggot.
I FUCKING HATE YOU OBESE FUCK XIAO.
