Tohko’s father was an Italian. Kirino was more likely Tohko’s mother’s surname but I will still leave the earlier translation as Mr. Kirino (but with a note) for ease of understanding as his name seems too difficult to decipher.
It’s written as アベーレ・アルトロマージ which directly reads as “Abere Arutoromaji”. My best guess is something like “Abelle Altromach” but Abelle seems more like a female name… >.>;;
I’m not familiar with Italian names myself, though. Any suggestion?
ETA: It is suggested (here, here and here) that the name is Abele Altoromagi. Thank you for all the helps, everyone! <3
