構成員最年少ながら人類女性の口説き方を他の構成員に指南するなど、プロ音楽集団初期の２年間を音楽的に牽引する。しかし「純粋で尖っている」ことを信条としすぎていたあまり、当時の産業化した日本の音楽界に疑問を抱き、体制に取り込まれる前に自らの意志で脱退。人間界に帰化し『Cats In Boots』で世界デビュー。酸いも甘いも体験し、最近では「音楽の中でだけ尖っていればいいや」という境地に達し、花の写真撮影が趣味になり、他の構成員に若手芸人を解説するようになる。酒もほとんど飲まなくなった。
聖飢魔IIには地球征服の前後、ほぼ５年おきにpart-time memberとして参加している。猫好き。 山登りと昆虫採集好き。依然として女好き（？）。
Chief of Staff. Preceding the earth debut of Seikima II, E.M.JAIL not only volunteered for his position, but was accepted because of his enthusiasm and talent as a guitarist. Although the youngest member of Seikima II, his talent at enthralling human women is so great that he often advises his fellow members on how to manipulate women’s hearts. In the two years he was originally with the band, he instigated many musical ideas and solidified the band’s sound. However, being a brutally honest person with very little tact, he became dissatisfied with the condition of the music scene. After fearing his own dissipation within said scene, he decided to leave the band. After naturalizing his status as human, he debuted internationally with the band, “Cats In Boots”. After experiencing many highs and lows, he decided that his brutality is best left in his music and not in his personal life. He became enraptured with the art of flower photography, and recently is in the practice of recommending and critiquing the acts of popular young comedians. He now drinks very little, as opposed to his past habits. Since the conquest of earth, he joins up as a “part-time member” roughly every five years or so. He is very fond of cats, mountain-climbing and the capture and collecting of rare insects. His one unchanging passion is…women?
