: Kaien's edited Shikai skills(the CS is still on 689, with a hider labeled Kaien.): 

Shikai appearance: [img=http://www.399animeshop.com/image_sal/Ulquiorra_Murcielago_Replica_with_stand_and_sheath.jpg] Ignore the stand and focus on the sword. 
Bankai appearance: Bankai not achieved. 

Shikai skills:
(Start off with no Shikai or 4 to 5 Shikai skills)
1. The blade is wrapped in shadows that take the shape of flames, allowing the blade to be instantaneously summoned from his shadow. This is purely a summoning ability and the flames are useless without Ability 3. They are however, a part of the Shikai appearance and do not dissipate until the sword is sealed.
2. Increased Strength (5 post use, Ten post cool down)
3. Through ability #1, Kaien can charge his Reiatsu into the flame-shadows and increase the striking power of his Zanpakutō . (2 post use, 3 post cool down) 
4. Increased Speed(2 post use, 3 post cooldown.)
