The Greatest Magicmaster's Retirement Plan: Volume 4

On the night before the Friendship Magical Tournament, Alus receives another mission.
Peaceful times for Alus and his friends come to an end, as Tesfia is forced to consider an engagement. Meanwhile, Alus has to face off against a strange attacker that suddenly appears at the Institute.
At a conference of the rulers of the seven nations, even Alpha’s beautiful ruler, Cicelnia, approaches Alus. When Alus is suddenly appointed to guard Cicelnia, he meets the other nations’ rulers and the Single Digits that guard them.
An uneasy atmosphere pervades the conference, as the nations vie for power.
With the Friendship Magical Tournament looming on the horizon—trouble stirs!
