Bundai

Driven by a desire for revenge after being left with an unpaid bar tab, this aggressive tutor employs brutal, unorthodox tactics to force Mugen into literacy. Using physical intimidation and psychological pressure, he subjects his student to a chaotic lesson involving punches and lectures on the "souls" of letters. Despite the violence, his high-intensity approach proves remarkably successful, enabling Mugen to master reading and writing in just one day and even inspire the creation of the infinity symbol.
