This article is about a/an villain in Shuriken Sentai Ninninger.

Mangetsu Kibaoni (牙鬼 萬月 Kibaoni Mangetsu?) is the son of Gengetsu Kibaoni and Ariake no Kata. He is the younger brother of Kyuemon Shingetsu Kibaoni.

Character History

Mangetsu was thought to be the firstborn of Gengetsu Kibaoni and Ariake no Kata. After coming out of his mother, he started stealing snacks from children. As the Ninningers meet him, Masakage tells them that Mangetsu is Kibaoni's son. Whining from one slash, Mangetsu tends to his mother to where Masakage summons Hyakkarage to attack the Ninningers. Later, Kasumi devises a plan to trap Mangetsu through baited snacks, but as he was captured, he soon shows his true self: a ruthless, manipulative, even abusive general. As he kept on beating Fuuka, this causes Kasumi great distress to where she couldn't even think properly. Later on, as they engage in another battle, Kasumi ends up taking Mangetsu down with Shishi-Oh's assistance. Mangetsu enlarges afterwards and as he was fighting Shurikenjin, Ariake summons Gashadokuros to deal with the ninjas for him. Mangetsu gets bothered by this but Masakage tells him that he's far too important to lose. Shinobi 39: Kibaoni's Son, Mangetsu Appears!

Enraged by his mother's action, Mangetsu starts beating up Ariake for ruining his fun. Masakage restrains him for this, but as Mangetsu was still in frustration, Ariake didn't seem to mind as he was getting as wild as his father. Later, Mangetsu decides to check in on an "unpleasant smell". Kyuemon tells Mangetsu that he is his father's page, but Mangetsu gets scrabbled at this and leaves. As Binbogami is finished off by the Ninningers, Mangetsu appears before them, attacks them, and takes Kasumi's invention. This leaves Kasumi furtherly pissed off as he took her invention. Mangetsu then attacks Kyuemon and uses the device to tell him the truth on what he really is, but as Kyuemon mentions a few words, he sparks at the device and vanishes.

As the Ninningers find at Kyuemon again, Masakage attacks them. Kyuemon then leaves the battle to the Ninningers. During the party, Mangetsu uses Super Advanced Yokai Shuten-douji against the Ninningers to fare at the games. Yet as Shishi-Oh assured their victory, in the giant battle, this left him drunk and evicted of his OtomoNin body. Mangetsu gains the opportunity to seize Shurikenjin and with Shuten-douji, takes down the ninjas. Maskage then tells Ariake the prophecy that Mangetsu is the chosen son that'll free his father Gengetsu and unleash him to the world. Later, he entrusts Shuten-douji and "Nekomata" (actually a disguised Tsumuji) to Shurikenjin while he fights the Ninningers. The Ninningers then soon take down Mangetsu in the ensuring battle and as they freed Shurikenjin from their clutches, Mangetsu and Shuten-douji enlarge themselves to fight them. With Yoshitaka also joining them, they soon use all their OtomoNin against them. The Ninningers take down Shuten-douji and as Ariake arrives with a Gashadokuro, Yoshitaka, Tsumuji, and Shishi-Oh uses HaOh Shurikenhin to take them down, with Mangetsu using his mother and the Gashadokuro as meat shields (though Ariake survives). Mangetsu laughs at this. The Ninningers get mad at him for this act with Mangetsu responding that he can use anything he wants, even his own parents. This causes them all to give in their all to finally take him down, and with the finishing strike from HaOh Gekiatsu Dai-Oh, Mangetsu tells his father that he wanted him. Back to normal size, Mangetsu is stumbling from the battle. Kyuemon tells him too bad and with Mangetsu asking who he is, Kyuemon tells him the foreboding secret - He is Gengetsu's first son and he is his older brother. Shocked by this, Mangetsu then turns to stone, leading to an explosion, but not before Kyuemon took his necklace.Shinobi 41: The Five Games of the Kibaoni Party!Shinobi 42: OtomoNin Wars!

Video Game appearances

Super Sentai Battle Base

Mangetsu Kibaoni is among the vast pantheon of villains which appear in the mobile game Super Sentai Battle Base.


Upon his introduction, Mangetsu pretends to be a buffoon, stealing snacks from children and being a poor warrior and a mama's boy. However, it's just an act to lower the Ninninger's guard down, mainly Kasumi's. His real personality is that of a cool, cunning, and manipulative warrior. Mangetsu also shows no respect to his mother, despite her trying to thoroughly support him, even to the point where he'd stomp on her for telling him to retreat.
