Barabaraman-sensei teaches the Apple class at Urara School. He exhibits distinct plant-based traits, growing roses in his hair during moments of excitement or strong emotion while his body remains covered in thorns. His abilities allow him to manipulate and generate plant life; anger specifically triggers the emergence of unsettling roots or vines. He actively participates in school events, such as a three-legged race where he partnered with Chacha, combining his botanical expertise with her magical boomerang for competitive advantage. While generally calm, his plant characteristics become visibly pronounced during rare irritation. He maintains professional interactions with colleagues within the school structure, including Rascal-sensei of the Banana class. The documented information provides no substantial character evolution, backstory, or details of appearances in spin-offs, films, or OVAs.
