After making a promise with Ameri, Iruma sets out to try to move up a rank. Iruma finds out that there is a promotion exam in a week where they would play execution cannonball, and he also finds out it’s rather similar to a game they play in the human world. Iruma decides to train after he realizes he’s far weaker than anyone else in his class. Iruma decides that he’s not going to use magic, so he starts an intense training regimen with Opera. What does Iruma gain at the end of all this training?
The first to enter their enemy's castle
 and eliminate everyone inside is the winner.
.من يقتحم قلعة عدوّه ويبيد الجميع في الدّاخل أوّلًا يفوز
Man begibt sich in die gegnerische Burg
El vencedor era quien eliminaba a todos
los habitantes del castillo del rival.
El vencedor era quien eliminaba a todos
los habitantes del castillo del rival.
Le but du jeu est d’exterminer
tous les démons du château ennemi !
Il vincitore è colui che entra nel castello 
avversario ed elimina tutti gli abitanti per primo.
Aquele que entrar no castelo inimigo e
eliminar todos primeiro é o vencedor.
Победителем становится тот, кто, ворвавшись
во вражеский замок, перебьёт там всех!
