Get it? Because one of the characters is a ghost? I’m going with the alternate name for this, since Another Shitty Sister Light Novel Adaptation is slightly more ridiculously long than the disappointingly sensible length of the official title.
A dumb, one-note OVA about somebody in a schoolgirl mascot costume transferring to Anime High School is something of a novel idea. Seeing her greet the class, turn down a smitten boy, and wistfully look out the window with the same overly-gleeful expression is just what the industry needs to shake things up. Instead, we get a dumb chastity belt show that relegates the brilliance of the schoolgirl mascot concept to the ED.
AnShiSiLiNoAda is the kind of show that thinks a little sister being molested/possessed by a lustful spirit wanting to bone her step-brother is enough to base a comedy around. That having her pass out multiple times in the same episode is the optimal means of scene progression. That having her desperately needing to piss, but being unable to for half an episode, is hilarious, rather than tedious and an insult to the intelligence of all but the simplest of life forms.
Barring somebody who’s had their head scraped against concrete nonstop for the last fourteen years, I don’t think there’s anybody watching AnShiSiLiNoAda expecting it to be entertaining in any capacity. Even so, I still didn’t want to discount it outright; perhaps there’s more to AnShiSiLiNoAda than piss jokes and token lesbianism. Ecchi has gotten somewhat more ambitious and creative over the years, moving past the paradigm of average chaste boy being thrown into compromising situation with hot co-eds, and his little sister. Now it runs the gamut of boys dressed like girls, girls dressed like boys who dress like girls, and everything in between. The variety of fetishes to make boring by framing with a variety of boring premises has never been greater.
Having an emotionally distant little sister intermittently possessed by an inexplicably amorous spirit seems like a natural progression of the formula. I’d like to think that it’s a commentary on the genre as a whole, and how a stepsister lusting for her older brother happens with as much frequency as spiritual possession. Or hell, maybe it’s a statement about the very nature of sexuality, and how the concept of chastity is, in and of itself, used as an unjust reason for fetishizing the fairer sex, regardless of relation—we, the audience, are Hiyori, forcing ourselves and our values on Mitsuki so that we might jump her step-brother’s bones. Or maybe AnShiSiLiNoAda is more positive, making note of the imouto’s necessity in an increasingly-globalized, impersonal society. After all, don’t we all need an imouto to get us through the day?
It would require a scholar more storied in the field of ecchi interpretation than I (hint to make Scamp or Shinmaru blog this, Cart Driver FAL winners) to even make out the murky depths of genius that AnShiSiLiNoAda is plumbing. So watch this shit.
