I went all in on Group C

After traveling through time, Kaiji gained the ability to buy and sell any person or group as if they were stocks.
So, after carefully selecting for a long time, Kaisi chose Crychic, which seemed to be thriving, as the first stock and went all in!
Hehehe, this is the peak of my life!
PS: This book is mainly about MYGO, with a little bit of fun stuff like Kurumi, Academy Idolmaster, and Ace Attorney.
