Welcome to Demon School! Iruma-Kun 3 (manga)

His first-ever personal goal reached, Iruma wonders what he should set his sights on next. Fortunately, there are a whole host of battlers, organized group demonic activities, that could provide the perfect pursuit. Doors open for Iruma at every turn, but do these Netherworldly clubs actually want him…or do they only want the magic in his ring? Iruma’s search for a battler where he belongs sends him crashing straight into a rare demon without magic, igniting the most explosive action yet!
