I think Shou will have to skip breaking into the Thunder HQ since he hasn't any clue how to do that besides walking in and asking to speak to someone while waving files around. He could make a good diversion if he does that.

As for the water plot, Shou will probably laugh a lot listen to the link, isn't that laugh just silly?. And then his accent will go from the Okinawa dialect to the street-ready Mallepa accent of a young gangster type. There will be hints of his regular accent but for anyone that knows the differences in Japanese dialects will really wonder since Mallepa is a city that mixes Chinese and Japanese and Taiwanese together in one big pot of wut.

Also his re-echo will be one about his agility, which might mean him wanting to test just how much he can do. I am also hoping that the book cover modeling will grant him another echo in the form of an old group photo of him and a bunch of strangers.

Otherwise, he's free for any plots that you may want to throw at him!
