|“|| Possibly a descendant of Ebisumaru.|
A weirdo who came from the future and got stuck in Edo. Apparently believes herself to be a beauty, and always has an eye on a good-looking guy.

Bismaru (シスタービスマル Shisutā Bisumaru?, "Sister Bismaru") is a crazy nun from future Neo Edo. He is an okama (cross-dresser/transvestite) who bares a striking resemblance to Ebisumaru, allegedly being his French-catholic descendant from the future, explaining why he is dressed like a mix between a nun and a miko/shrine priestess.
He made his debut in Ganbare Goemon 3: Shishijūrokubē no Karakuri Manji Gatame, and later reappeared in Goemon's Great Adventure.
Sister Bismaru kidnaps the Wise Old Man when he was visiting the future while testing his new time-traveling machine, and somehow gets himself stuck in modern day Edo. Goemon and his friends decide to set on their way in order to stop him and save the old man.
He tries to take over the world by siding with Lord Jurokubei, King of the Underworld, and appears several times throughout the game, either to taunt our heroes or even in a giant robot boss fight while piloting the Bis maru Elegant.
At the end, he is seen trying to comfort Jurokubei after he is defeated, although for all response he is thrown away, presumably returning back to the Underworld.
He is later seen with Dochuki, although he is once again thrown away with Dochuki's psychic powers. He then reappears at the end when Ebisumaru's daughter (presumably) presses "summon again" on the machine.
- In the English version of Goemon's Great Adventure, one of the characters refers to Bismaru as a "he".
