Gekkou

Profile
A legendary ninja who served under the previous Oda Nobunaga and died during the Youkai war. He found Shinobu as a baby on the battlefield and has loved her more than anything else in the world ever since, to the point of cutting his own left arm off so that they could never be apart on the battlefield. Ultimately, he blew himself and Shinobu up after she sustained critical injuries during the Youkai war, killing them both.

In Sengoku Rance, it is possible to recruit him in a second play through, where it is revealed that he and Shinobu were struck by a bolt of lightning before their fatal explosion, sending the two into the future where they promptly serve the current Oda Nobunaga.

If Omachi is recruited, he will attempt to avenge his former lord by assassinating her, but changes his mind after seeing that she truly did change her ways. This appearance is entirely non-canon and has no bearing on the current timeline.

Trivia
- If he is the only unit deployed into battle after getting character cleared, he will blow himself and Shinobu up to defeat the enemy, mirroring their previous sacrifice and killing the two off for good.

- The current Ninja King Inukai served under Gekkou when he was a rookie ninja, where he referred to him as "boss". Inukai still fears Gekkou's harsh training to this day to the point where he'll surrender to Oda immediately after finding out that Gekkou is with them.

- His special skill "Assassination Skill +" that gives him 100% chance to kill an enemy that has run out of action points in Sengoku Rance may reference to both Gekkou and Shinobu roles in Kichikuou Rance where they can only assassinate "tired" Leazas generals (already took orders from player in that turn).

Sengoku Rance
During the events of Sengoku Rance, if you sent only his unit to attack a terrority, there will be a talk event between him & Shinobu. He will automatically self-destruct, allowing you to capture a city of the terrority easily but you will lose him forever. Gekko must be character cleared for this to happen.
