The Devil Is a Part-Timer!, Vol. 22 (manga)

TROUBLE WITH STAFF!The path to becoming Devil King is not easy-it's one thing to challenge the chief of a single clan, but attempting to unify all demons means venturing into uncharted territory. Young Satan may have won over the chiefs through trickery and clever schemes, but tensions are rising with the new addition of the Iron Scorpions. When Lucifer grows tired of playing along, the Devil King's army may be in imminent danger of collapse!
