Goemon Ishikawa XIII

Goemon Ishikawa XIII (十三代目 石川 五ェ門 Jūsan-daime Ishikawa Goemon) is the thirteenth generation of renegade samurai, a descendant of the historical figure Ishikawa Goemon.

He is famous for a reticent personality coupled by apparent unlimited skill in martial arts and swordsmanship with his sword Ryusei (流星 Ryūsei), known in the anime as Zantetsuken (斬鉄剣). A partner with Arsène Lupin III and Daisuke Jigen, he tends to join their exploits only on a when-interested basis.
