As the name of the set suggest, this set will contain the CSM versions of the Lock Seeds used by the Kureshima brothers. The Lock Seeds that are confirmed included in the set thus far are: Kamen Rider Ryugen's Budou Lock Seed and Kamen Rider Zangetsu's Melon and Kachidoki Lock Seeds.
All of these items are compatible with the recently released CSM Sengoku Driver set or if you are saving money, the soon to be released CSM Sengoku Driver Project Ark Edition.
