Monochrome Factor is a shonen-ai fantasy that squanders a promising storyline and ends up leaving the viewer bored and frustrated.
The plot premise is surprisingly good. Nikaido Akira, the Chosen One (in an alarming deviation from the norm, a Japanese schoolboy!) is attacked by demons, forced into a contract by a mysterious stranger, Shirogane, and subsequently battles the forces of evil along with his school friends, whose powers conveniently 'awaken'. Goodness, it's exactly like Bleach! And 3/4 of the shonen series out there. This isn't necessarily a criticism, (if it works, why fix it?) but boring. In the first six episodes, Akira fights demons and recruits his team members. So far, so good. There then follows 15 EPISODES OF FILLER. Let me repeat that. 15 EPISODES, which serve to advance the plot in NO SIGNIFICANT WAY. AT ALL. My capitalisation expresses my disappointment on this front. Every episode involves a (amusingly sexually confused - see below) guest star, who interacts pointlessly with the main group, becomes possessed, fights the group, is snapped out of it by his friend/lover/family/dentist, then cries and becomes a better person. Episodic doesn't cover it. Repetitive as hell. I got to Episode 21, and still there was no sign of the main plot, in a 24 episode series! The ending is predictable. Overall, there are gaping plot holes, a curiously impotent and motive-less evil force, and as always, a cast baddie for each cast goodie to fight so that hero goodie can fight arch baddie.
The animation is, however, very good. Or, if you're being less charitable, as good as you would expect a 2008 Genco production. It was good, though. As expected of a shonen-ai, the show is bishie-tastic, with a lot of pretty men fulfilling most major requirements. The young one, the brash one, the mysterious one - and all with broad shoulders and teeny waists. Perfect. Backgrounds are however serviceable at best, with little attempt made to ever impart a sense of beauty. Art Monochrome Factor ain't. I should note, however, that Akira's outfit in his 'Shin' form is one of the best I have ever seen for the hero of any anime. I have the urge to cosplay!
The sound is the same as the background. Utterly unnoticeable, it serves only to frame the 'characters'. The op is your typical shonen; fast and angsty without being something you would ever choose to listen to again. Ed is unmemorability defined.
The characters are clearly the point to this anime, where plot is central to Code Geass, animation to Red Garden, and sound to Nodame Cantabile (generalisations, I know - incidentally those are GOOD examples of anime). The characters are stereotypical but still quite charming. Stupid male sidekick, aggressive female, genius boy... stop me if any of this is new. As a shonen-ai, females get a very bad deal. In particular, Kengo's sister, Mayu, is both a comedy foil and a 'light-hearted' assault on woman-kind. Big-breasted, shallow, vapid, falling for man after man, the series goes out of its way to show that there is nothing sacred about heterosexual love. The queer credentials of Monochrome Factor are show-cased, with transvestites, lesbians and every gender bender you can think of.
Monochrome Factor however fails dismally on two counts. One, there is no character development. At all. None. Not a single character, in ANY WAY (caps again!) CHANGES AT ALL. Secondly, for a shonen-ai, the relationship between Akira and Shirogane is unconvincing. Shirogane in particular fails to move the watcher in the slightest, and spends 22 episodes leching on Akira, who could up till then be entirely straight, for all we know. There is zero emotional depth between the two, which means the viewer couldn't care less, something even Gakuen Heaven manages!
Overall, the series is deeply disappointing. If you watch the first six episodes, I heartily recommend you skip to Episode 22, and it would not make an iota of difference. As fantasy Monochrome Factor is derivative and has goddamnawful pacing, and as shonen-ai Monochrome Factor concerns an effete weirdo trying to touch a schoolboy for twenty episodes. Rarely have I watched an anime and wanted it to end.
