I don't like it primarily because the entire thing revolves around wordplay. For example, in Episode 3, Shannon and Kanon's deaths were confirmed with red text. However, that only counts for their personalities, not Yasu! It's annoying.
Also, What is Yasu/Shannon/Kanon/Beato/whatever elses real appearance supposed to look like? In the real world, that is, how Battler and everyone else perceive her physical appearance. Did she always look like Shannon to them? Or did she look like Yasu to them from the start, but Ryu07 just went with Shannon's appearance instead to mess with people, i.e. the readers?
