I reeeeeeeeeeeeeeeeeeeally hope the mangaka brings Garo back! I loved that guy, loved his cool mature ikeman vibe and how you'd always wonder just what that guy's thinking (similar to totonou.) And also Totonou getting a new friend he can talk to just sounds nice, I like their interactions - insert marge meme holding a potato "I just think they're neat!"
(And last but not least Garo's last questions for totonou, about him being like a kid wanting attention from someone, if he ever had to choose over his family... and also the way he responds to stress and fear - immediately curling up into a defensive ball, almost like a kid cowering to protect himself *eyes emoji* more backstory lore??
