page 22 : his jacket has the letter K , short for Koga .
page 26 , last panel : i think there is a mis-translation . kosuke is the name of the glass guy , so he should say this instead : ... k ... koga ... ? your face is scary .
so koga must have eidetic memory , he can remember the face of a guy that he met 3 years ago . i cant even remember the faces of my own family after i just met them 3 minutes ago , lol .
