Keishirou is one of the Kyougetsu clan members who joined the Eastern Expedition alongside his sister, Sakuya, to overthrow and take back the land from the Yatsukahagi.
During the skirmish, he would later find out that he is the reincarnation of Wilhelm Ehrenburg, and will constantly rely on his power, putting his sister in danger until his battle against Sukuna, a battle which would lead him to rejecting his old self.
Later on, Tengu Dou, a God bent on destroying all of existence due to his desire, completed his Law, forcing every living being to kill each other. Keishirou and his sister, who were ambushed, managed to survive the onslaught and even liberate themselves from Hajun's desire, an action that will lead to the fall of the Sixth Heaven and the rise of the Seventh Heaven.

Fought against Habaki.

Standard Equipment: A set of black daggers
Intelligence: Skilled combatant, able to keep up with the likes of Soujirou and Shiori as well as Habaki and later the Tenma's. Able to utilize his Distortion Magatsuki and later Tenma Kessenka well in combat.
Weaknesses: When using Tenma Kessenka, Keishirou was only initially able to absorb anything through physical touch due to having manifested as a Gudou-Type ability (this is mitigated by him replicating Qliphoth Bacikal and using the absorption abilities on the stakes themselves by shooting them as projectiles). His Distortion, Magatsuki, cause a rebounding effect on his sister, Sakuya, and does damage to her to correct the causation caused by it.
- Magatsuki: Keishirou’s first Distortion, and one he shares with his sister Sakuya. When activated, it allows Keishirou to absorb misfortune around him and then redirect it towards his foes, cursing them with bad luck. Magatsuki can also cause extremely improbable events to happen in his favor, such as causing lightning to strike his foes in the middle of a snowstorm or have them lose their footing while moving away to dodge his attacks.
- Tenma Kessenka: Keishirou’s second Distortion, gained after losing his first one, Magatsuki. Tenma Kessenka is the Gudou form of Keishirou’s Briah from his past incarnation as Wilhelm Ehrenberg: Der Rosenkavalier Schwarzwald. Much like Wilhelm’s Briah, Keishirou’s Distortion allows him to absorb anything, including one’s good fortune (i.e. he can absorb a person’s fortune and thus will only be able to suffer minor wounds while his opponent will suffer major wounds). However, due to manifesting as a Gudou-type ability, Keishirou can only affect people and other things by physically touching them under normal circumstances. In addition, Tenma Kessenka allows Keishirou to replicate Qliphoth Bacikal, Wilhelm’s Relic; albeit, not as powerful as Kaziklu Bey's Relic from the previous world. He can use the stakes his Relic generates as long-range projectiles that also apply the effects of his Distortion, greatly extending his effective range and subverting his initial limitations.
