An interesting premise weighed down with clutter and clunk.
Shiro's dad teaches at St. Kleio's, a school for clones. Yes, you read that right: all the other students are clones of famous historical figures, including Napoleon, Mozart, Freud, Joan of Arc, and other notable personages. The teenage clones are at St. Kleio's to develop into mature adult versions of their original selves, but nobody's really sure why Shiro's there with them (assuming it's not the tuition break he's most likely get as the son of a staff member).
Not too odd a premise for a sci-fi story, but then it gets weirder. Marie Curie decides she'd rather play piano than study physics. The JFK clone is assassinated. Freaked out, some of the clones develop their own magico-religious practices. Shiro's dad is acting shady, armed guards are patrolling the halls, and a secret group of some sort has declared its intention to murder all the clones. Much like Shiro, the reader is left to bumble through the story wondering what's going on.
What could have been a neat story is thwarted by what, for me, were a number of deal-breakers:
1. All the great women of history - including Curie, Florence Nightingale, Empress Cixi, Queen Elizabeth, and others--are portrayed as simpering idiots. Now, granted, these are teens we're talking about, but all the male clones get to be just as intelligent and forceful as their adult counterparts. Teen Freud is conversant in psychoanalytic techniques. Teen Mozart is still a genius pianist and composer. Teen Napoleon is a strategic thinker. Teen Einstein is brainy. The girls, however, are simply there to be T&A (I know fan service is a thing, but its presence here was pointless and stupid). Teen Elizabeth pouts because she wants to get married and have children instead of being a ruler. Empress Cixi is only concerned with how pretty she is. And teen Florence Nightingale made me want to gouge my eyes out, as all she did was talk baby-talk and coo a lot. Not cool.
2. Suekane went there and included teen Hitler. Why would you do that? Nothing good can come of this. Don't even ask me to feel sorry for teen clone Hitler. Not gonna happen. It reeks a little too much of trying to redeem the irredeemable, and will be upsetting AF for Jewish readers.
3. A first volume is expected to have exposition and set up future storylines, but Suekane basically throws a whole lot of weirdness at you and asks you to care. And to be honest, I really don't. None of these characters are remotely sympathetic, not even Shiro, the nominal protagonist. I think we're supposed to feel sorry for him because he's the lone human amongst all those clones, but there's nothing in his personality to hang your hat on, so to speak.
The target audience for this will not notice, or care, half the things that annoyed me about this manga, but with so many great series out there to choose from, you can let this one slide by and focus on better-quality work. I will most likely read one more volume to see if it gets any better, but it will have to be a hell of an improvement/turn-around for me to revise my opinion.
