I like the small detail that the "pop-out" version of the kanji that Shii made has a couple of strokes that are bent the wrong way, as though it's something that was moulded/sculpted by a high-schooler who has made an excellent attempt for a first-timer but with still some room for improvement. Makes it feel a little more real even if the whole concept of the club is a bit absurdist.
Also, is Shii's name short for anything longer like how "Kimi" is short for "Kimidori"?
