This Detective Conan OVA is a simple, fun, little side-story. One that doesn't take itself too seriously, and where nothing important happens, but it still manages to be enjoyable enough. Part of why nothing important happens is because instead of an actual case, the story revolves around Sonoko's murder mystery that she's writing for a school play. We get some interesting interpretations of how the case is solved from each of the main characters, and most of their deductions are pretty funny. However, with the lack of a real case to solve, the story ends up feeling a bit empty. Still, the story wraps up inthe end, and the whole thing feels complete.

The art and sound design are both passable, and are on the same level as the TV show at the time this was released.
Also, the characters are still well-written, and come off as interesting.

However, the story is the main focus here, and it comes off as generally tepid and uninteresting, leaving us with a competent, somewhat fun, but ultimately flawed episode. I'd recommend it for anybody who is a fan of the show already, but for anybody else, it's not interesting enough to warrant viewing it on it's own.
