Mass for the Dead Arc
To prepare for an event where invaders raided the 9th Floor and the Floor Guardiana were unable to respond, Albedo organized a defense training to simulate such a raid. Achu and his colleague Unchu participated in the drill, serving as guards to the Momonga's personal apartment alongside the Pleiades led by Sebas Tian. Achu and Unchu were bypassed by the Shalltear Bloodfallen who used [Perfect Unknowable] to slip past them and enter into the apartment.

After the drill was over Achu attended a review session of the drill led by Momonga and Albedo. Due to the training's success Albedo recommended in continuing raid training at unannounced intervals. He and Achu, and the Eight-Edge Assassins agreed to the proposal.

Much later Albedo, while working as a maid for Momonga was permitted entry in the Overlord's quarters by Achu and Unchu. While everything seem peaceful they were alerted by the Eight-Edge Assassins in the room calling for help. Rushing to the aid of their fellow guards they found Albedo attempting to sexually force herself on Momonga. Before Achu and Unchu could stop her, she incapacitated him and the other guards.

Achu later recovered after Shalltear intervened in the incident, saving Momonga from Albedo's clutches. He was present along with Unchu and the Eight-Edge Assassins on guard when Albedo was brought before Momonga to stand for her actions.
