Why do you link this emmediatly to 'It must be resonating to Shinso!' There is literally no proof nor anything to base that on... ._.

In all honesty there are way more logical theories when you read some comments on some other sites that release chapters. This all just seems waaaaaaaaay over the top for me to be even remotely well based. For all we know this is your typical shounen moment where the main char's energy/powers go berserk and out of control because of typical shounen stuff.
