## Chronology

### Mass for the Dead Arc

*Main article: Mass for the Dead Arc*
To prepare for an event where invaders raided the 9th Floor and the Floor Guardians were unable to respond, Albedo organized a defense training to simulate such a raid. Both 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 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 seemed 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.

Due to their lack of action in guarding Momonga's quarters, Achu and his comrade Unchu were beginning to get bored with their assignment. Later after hearing word about the Miyoshi-kun Cup, Unchu and Achu made a request to Momonga so that they could be included in the Cup as obstacles. To sate their warrior spirits, Momonga arranged for the next Cup venue to involve them fighting the Cup contenders.

Achu and his partner Unchu were present in the replica of the Throne Room of Fake Nazarick, attending the start of National Foundation Day Ceremony with the other denizens of Nazarick and the Sorcerer Kingdom.
