I miss the old days when Takara TFs came with self-addressed feedback survey cards that gave you the option to recommend up to 3 Transformers that you would like to see made in the future (e.g.: as MP, BT, reissue etc.). Nowadays it's all done online and the character recommendation option isn't there.

What's the meaning of "kaiden"? Sounds to me like the Japanese word for 'initiation' (皆伝)
