Summary

Onsen-Mark serves as one of Ataru’s instructors at Tomobiki High, though his tenure is defined by a profound sense of melancholy. This middle-aged educator’s sole passion lies in delivering his lessons, a goal he is consistently thwarted by the chaotic interruptions caused by his students. His classroom is frequently left in ruins, often destroyed by Lum, Ten, or Shinobu, rendering his teaching efforts futile. True to his name, which translates to "Mark of the Hot Springs," he typically dresses in shirts featuring hot spring motifs.
