ALL the techs

Katsuo already had 2 unused tech slots, the third one is from when he leveled up to AD-1

For: Sigil
Name: Hikitomeru (Detain)
Type: Passive
Cost: High
Range: All
Description: Katsuo creates a large box made of blue light which entraps both himself and his opponent. It is roughly the size of a football field. If an opponent touches one of the walls or ceiling, they will be attacked by blue flames and a repulsive force. However, if the opponent has HAN 5+ or more than Katsuo's SEI, the flames will have little effect. Since Katsuo cannot be burned by his own flames, he is only effected by the repulsion if he happens to touch a wall or the ceiling. The floor does not burn anyone, only acting as a solid surface to stand on. This box will not disappear unless Katsuo wills it or loses consciousness. Only those with REI 5+ or higher than Katsuo's SEI can leave the box. This can only be used once per battle.

Description: Katsuo creates a duplicate of Aokishi made of blue flames in his free hand. It only duplicates the shape of the blade. The flames it is made of carry the same properties (won't have much effect against someone with 5+ or more HAN than Katsuo's SEI).

For: Sigil
Name: Akenomyōsei (Morning Star)
Type: Passive | Duration: 5 posts | Cooldown: 4 posts
Cost: Medium
Range: Self
Description: Katsuo gains large wings made of blue flame. They are similar to an angel's wings and grant him the ability to fly for a specified amount of time. They cannot be destroyed by physical attacks because they are made of fire and will simply reform, also burning any organic material they touch. However, spiritual attacks of a high level (opponent's SEI +5 or higher than Katsuo's SEI) can blow them away.
