- Name: Sacred Energy Armor (気鋼闘衣, Kikōtō'i; translated as "Energy Steel Combat Cloth")
- Type: Seikouki; Kyūseijutsu; Short Range; Defensive
- Rank: A
- User: Seireitou Kawahiru
Surrounding his body with Sacred Energy, Seireitou can create two forms of battle armor; one for defense, the other for offense. While using the first suit of armor, Seireitou was able to dominate Koukon by himself (albeit they were already battle-weakened). But despite all that, Seireitou's Sacred Energy Armor was not strong enough to defend against Ryun's fully-charged Four-Tailed Monkey Menacing Ball after his training with Sasuke.
