Synopsis

Leehan experiments with water magic, inadvertently discovering that spinning a water ball increases its piercing power. He then uses invisibility to bypass a golem, noting that it ignores invisible figures and also doesn't react to him once he crosses a certain boundary. The students attempt to attack the golem's core, but its protective measures render the attempt useless. Meanwhile, the professors nonchalantly observe, seemingly confident in the students' ability to handle the situation despite past claims that they're just teaching first year students, with one professor revealing that Leehan had been learning from her grimoire.
