Mr. Kagoshima arrived at Arama Academy as a new teacher in episode 56, filling the vacancy left by Mr. Fukuoka. He becomes one of multiple colleagues vying for Miss Machiko's affections, engaging in a noticeable rivalry with fellow teacher Mr. Yamagata. Their competition plays out in episodes like a skiing trip where Mr. Yamagata gained an advantage by successfully executing a double flip.

His presence sparked curiosity among the students, particularly the girls, who embarked on a storyline dedicated to uncovering his secrets. His interactions include an incident where the mischievous student Kenta tricked him into lighting a cigarette, which subsequently ignited an improvised explosive device.
