Well,I like to see that Shisui in event in general,not only in shady RNG wheels.I might be wrong,but I think Shisui come before Kimimaro halloween,but now Kimi is in events for collecting frags,and Shisui is keep behind "luck" wall.

Oh,sorry. But kimono Shisui got BT in China,there is no way they give him for free,when they can milk some $ extra.
