Barrierfreeman's young body. Because he is a young Chojin Wrestler he is inexperienced with power and strength and barely won any matches. Just as he is about to give up he comes across Jejo-man in the tree he was sealed in and is conned into merging to become Barrierfreeman. At first he is always bickering with and defying Jejo-man, but by the Demon Seed Arc he has matured into a calmer Seigi Choujin. In the Dream Chojin Tag Arc he teams up with Ilioukhine and become the Fireball Flying Fogey Squad.
In the Japanese Ending Credits he is listed as Barrierfreeman N (バリアフリーマンＮ).
