@azerez I thought it was assumed she was nice. Kaiji seemed to be more worried about her seeing his scar (i.e. seeing what he's become) than just meeting her
Well, aside from wanting to take a bath with me, this is... very similar type of behavior to what I'd expect from my own mother. Ecstatic to see me, happy to "play along" with anything....
Kaiji's mom is adorable. Also, many people in the comments section not understanding that families bathing together is a cultural norm in Japan, pretty hilarious.
