Takashi Seishin is a shinobi bounty hunter that collects bounty on high priority targets. He is the last remaining clansman of the Seishin Clan after his clan was brutally slain by Kumogakure for profit. As a result Takashi became hellbent on destroying Kumogakure and eventually met Sasuke Uchiha who was travelling. Sasuke sympathized with Takashi's desires and took him on as an apprentice, however Sasuke attempted to try and derail Takashi from his path of revenge. Eventually becoming strong enough they parted ways, but Takashi still desired to destroy Kumo and before Darui left for the Gokage meeting and Chunin Exams to be held in Konohagakure, Takashi showed up to assassinate him and succeeded in destroying Kumo.
