'Conductor' does surprisingly well with fairly weak-seeming material. The protagonist and supporting characters are nothing you haven't seen before: plucky and well-meaning female lead, cool genius with a heart of gold, severe (and severely wealthy) musical prodigy... Nonetheless, I was led to genuinely care about their travails at least to some degree, and the repressed-memory twist is well-executed if very pulpy. I'd have liked Naomi to be more proactive, but her emotional life was well-drawn and I cared about her wellbeing more than her objectively-more-interesting supporting cast. If you like campus novels/manga, Gothic melodrama (especially of the modern kind) and conspiracy mysteries, this isn't a baddiversion at all; particularly since it's only twelve chapters long.

[SPOILERS BEYOND THIS POINT]
I found the climactic twist extremely obvious, all the way up to calling the death of a major character leading into Act 3 - but it didn't help that an important character is displayed on the cover such that it's not hard to guess.

Might also have been nice to have a few more chapters to develop the relationships between the core five, *especially* Takumi and Naomi; but all the protagonists suffer. A deeper, 'Secret History'-style look into their psyche would have benefited all of them.
