Ishi -> StoneTripleJMaster3 said:P.S.
Found the reference in the Manga, but honestly the version I read I could see how it might have gone unnoticed. Puck says "ahhh so Ishidori!?" "A Robber... Who Throws...Stones?" Still not sure where the meaning comes from so if someone knows more about it I would love to know. Couldn't find much in my search through the archives although I will admit searching by name and meaning brings up extensive unrelated results so forgive me if it's already been discussed in another thread.
Dorobo -> Thief
Combine both and you get Isidro.
