User blog:P.H. CP/Possible Next Card-Jitsu plot?

I Was Checking this week CP News but then i find something suspicious about Card-Jitsu

Sensei told that he have her on sensei and ninja friends and then he go in a journey etc.But then comes the bomb:he battle against an Great Danger with their friends and sealed away the danger then he become sensei



Remember that Sensei say that he was training with Tusk when the accident with them happened.So this means that Great Danger was defeated after he lost Tusk.Maybe Tusk and that Great Danger attack the Dojo together? or is just this history coincidence?
