Catgirl Summoning: The Neko Has Landed
The beginning of a typical Magic School Catgirl Ecchi Anime:
A know-it-all nerd-boy wizardry student and house monitor confiscates a dangerous summoning scroll pilfered by a fellow student. The scroll seems to be for summoning a succubus, presumably from hell, as this is the dominating tradition locally. The student cannot resist taking a peek a the scroll contents and ends up completing the spell.
A naked cat girl appears. Her unearthly sexiness is indeed that of a succubus. Luckily for our student she is bound in magical chains and he is initially able to keep his distance and resist her advances.
The cat girl appear remarkably happy with the situation and acts friendly although her language is a bit hard to understand. She is however not happy about the student's unwillingness to become more intimate.
The student is attracted to her but fears for his immortal soul should he give in to temptation. Even worse, his pride would be shattered as his often vocalized opinion of devil-worshipers is "weak-willed deluded fools". Also having read the stolen scroll he imagines himself being expelled if found out.
