Summon Oni
Among the most hazardous spells in the maho-tsukai’s repertoire, this spell summons forth an oni from Jigoku. The oni appears anywhere the caster desires within the range of the spell, and must immediately be given a name - either the caster’s own name or the name of another person closely connected to the caster (a close friend, immediate blood relative, or someone who owes the caster their life) - or it will simply depart back to Jigoku. A name, however, anchors the oni into Ningen-do and allows it to remain within the mortal realm.
