Tsuno Kaimen

Tsuno Kaimen was a Tsuno Soultwister, student of Tsuno Kira.

Studying the Humans
His sensei Kira was studying the humans, seeking any weakness to exploit in their enemies. The only human available in the Shadowlands were Bloodspeakers and Lost, but Kira wished to expand her studies to the untainted samurai of Rokugan.

Deception
Kira cast a powerful spell upon Kaimen, who had masked Kaimen's Taint and changed his shape. As a drawback, the change caused him constant pain and would kill him. In the persona of Kuni Morihei, the tsuno visited a village, a few miles southwest of Kyuden Hida, disguised as a wandering shugenja.

Death
In 1165 Kaimen lured a group of samurai to the wilderness, near a cave. Inside both Tsuno managed to subdued them, and tortured each party member in an attempt to learn their weaknesses. The remains of the disguised Kaimen were found by a pair of Kuni Witch Hunters, who quickly tracked down the group. Kira was the only Tsuno who escaped through a portal into Toshigoku with her information.
