As the name of the set suggest, this set will contain the CSM versions of the Lock Seeds used by members of the Yggdrasill Corporation as seen in the TV series and the spin-off films. The Lock Seeds that are confirmed included in the set thus far are: Kurokake Troopers' Matsubokkuri Lock Seed, Kamen Rider Saver's Zakuro Lock Seed, and Kamen Rider Duke's Lemon Lock Seed.
All of these items are compatible with the CSM Sengoku Driver set or if you are saving money, the CSM Sengoku Driver Project Ark Edition.
