Tsugumomo Wiki

Yasuki Yatsukawa (八津川やすき, Yatsugawa Yasuki) is a bow tsugumomo and a member of Mayoiga.



Yasuki is very stoic, expressing little emotion and performing his tasks diligently. He is very protective of Mimane.


When Akito and Arumi Ashimine first entered Mayoiga, Yasuki fired arrows at them on site. Arumi was able to use her powers to predict his shots, helping Akito avoid his attacks. Their fight was interrupted by Mimane Miyou who excitedly and curiously approached the newcomers. Akito and Arumi were introduced to Tanmen and the other members of Mayoiga. Tanmen apologized on Yasuki's behalf, but when told to apologize himself, Yasuki remained silent. Yasuki would later apologize to Akito, stating Mimane getting too excited about the outside world whenever newcomers arrive as his reason.[1]

Yasuki accompanied Akito, Arumi, Mimane, Chikage and Shinshou to capture the black mass that Arumi saw in her divination. After a few years in their capture, the mass would reveal itself as Azami. Azami gave them the information they required about a weakened god from whom they could take a Stone Shard from, providing them a plan to carry out their goals under the condition they follow her terms. Yasuki, Akito, Arumi and Mimane stationed themselves in Kamioka as per Azami's plan, going undercover at Kamioka East Middle School.[2]

Yasuki asks Akito if they can trust Azami, to which Akito states they have no other choice and she has been correct so far.[4]

After returning from the arcade with Mimane, Akito explains to Yasuki and Arumi that Mimane revealed her identity to Kazuya and Kiriha. Yasuki tells Akito he has gotten too relaxed. Some time later, Akito tells Yasuki that he has been blackmailed by Kiriha into joining her and Kazuya's club.[5] After gaining approval to do so from Azami, Yasuki warns Akito of the danger os joining the club and to be watchful of Mimane's behavior. After their first day at the club and observing their target Kukuri in person, Akito tells Yasuki what happened. Yasuki asks about Mimane's whereabouts only for them to realize Mimane is not present.[6]

Mimane returns, telling the three about an attack from other members of Mayoiga, who are identified as Genbu, Kyouka, Jungou and Senga. Yasuki suggests they should take the chance to strike and join them in the assault on Kukuri. Mimane tells them otherwise, telling them that Kukuri is still too powerful for all of them combined. They decide continue with Azami's plan and Akito and Mimane go out to fight against the Mayoiga invaders.[7]

Shien creates smoke platforms for Yasuki and Mimane to use as they battle in the air. Yasuki warns Honoka if she attempts to leave, they will begin interfering with the local exorcist and gods who are attempting to suppress aberrations caused by the increase in cursed created by their battle.[9] As Yasuki battle's Honoka's projection, Mayoiga's ship suddenly reveals itself. Yasuki calls out to Mifune who tells them that Miurahi's power has disappeared and he can no longer maintain the ship. The ship collapses and the its passenger begin reverting back to their original forms as they fall.
