|Ryubi no Jōmon|
|English||The Gate of Dragon Tail|
Ryubi no Jōmon (竜尾の城門, The Gate of Dragon Tail) is a Kidō spell. It was one of the techniques used by Hachigen Ushōda during an attempt to defeat Baraggan Louisenbairn. While both the number and classification of this particular spell is not expressly stated, it most resembles a Bakudō (binding) spell.
Ryubi no Jomon creates over a dozen pillars, which are arranged by hand gestures, making them form a gigantic shield or door like barrier between the caster and the opponent. It can be used together with Koko no Jōmon, Kikai no Jōmon, and Hoyoku no Jōmon to form Shiji no Saimon. 
Brethren-in-arms withdrawing for the distance of 8 sun and standing still; blue bolt, white bolt, black bolt, red bolt; sinking into the ocean together seeking redemption.
