They dont know that. Its just what they tell people so they acept him living with the student instead of telling people they are compleat strangers
Ohhh ok thx
After Kiku was looking into some photo album, a blink of memory came out when he was seeing a old photo(taken by him) of Shirou's Grand father. Then he started remember everything( the manga's pace went to the past to show Kiku and Shirou's grandfafher relationship). I still dont know his name, i cant understand(Kiku is grandpas name)
i think i might confuse you, but Kiku(black hair guy) only has this name bc he doesnt remember his own name and that's Shirou gave to him. Actually, Kiku is the name of Shirou's grandpa.
I still dont know the black hair guy real name.
How did they know he was related to the grandad again? Link? Thx!
