Las name for Japanese Character

hii, so I have this character named luca (ironic bc my name is luka lol) and he’s half Japanese. I am looking for a shot, cute Japanese last name that fits the name. His personality is pretty much a shy, feminine guy thats quite sensible and nerdy.

You said you wanted short Japanese last names so I chose short names listed below. Personally, I think [name_u]Luca[/name_u] Sato or [name_u]Luca[/name_u] Imai sound well together.

Sato
Ito
[name_u]Kato[/name_u]
Imai
[name_f]Ono[/name_f]
Ando
Kudo
[name_f]Hara[/name_f]
Wada
