OK. So take a supernatural Urban Fantasy, Harem Genre-style anime, and throw in a magical Humongous Mecha. That's Asura Cryin'.Tomoharu Natsume one day receives a mysterious package from Shuri, a friend of his older brother. This box, called the Extractor, is sought after by many. At the same time, Tomoharu has to keep secret the fact that his childhood friend, Misao, is constantly hovering, ghostlike, beside him. Then a miko with heterochromia breaks into his house searching for the Extractor. After a fight breaks out in his house, he opens the box. What lies within is a mecha-like creature called the Asura Machina. That is only the beginning.Asura Cryin' is based on a series of Light Novels, animated by Seven Arcs in the spring of 2009, with a second season following in the fall.Do not confuse with Asura's Wrath, though on the other hand, the main character of that series is mechanical in a sense as well.Tropes include:
Then karma bites said Big Bad out and the presumed Big Bad was not the Big Bad after all.
Dude, She's Like, in a Coma! — When Shuri passes out (also, she has amnesia) Tomo wants to help her get into bed, but he wears a blindfold and has Misao guide him what to do with her voice so she makes sure he doesn't see or touch anything he's not supposed to. He still gets a nosebleed when she wakes up, though.
Expendable Alternate Universe — In this case, it's actually the "main" universe that we see get sent to hell. It turns out the first world holds several answers, as well as letting the audience see several characters who were dead in the second world be alive in this one.
Forgot About His Powers — Tomoharu. In the fourth episode he learns about how to become an Asura Cryin', but even when others of this kind are wreaking havok, Tomoharu holds out on making a contract with Kanade until the very end. In reality, he could have gained the power that could have resolved everything much earlier and with much less suffering. See Idiot Plot.
Future Badass — From another world, but Tomoharu-1 is a much more serious version of Tomoharu-2.
The Power of Love — A twisted version. Demons, when they find a contractor, get their power by sapping their contractor's ability to love. Not that the alternative is any better.
Later played straight when Kurogane literally becomes harem-powered. And on on fire.
Red String of Fate — A variation. A red ribbon ties together Kanade and Tomoharu as they're practicing for a three-legged race. Then Kanade ties it really tight. Then a superglue splashes on it, forcing them to stay together. Even when Kanade needs to take a shower...
Try Kiyomi from the 1st Student Government. He's WAAAAY more of a Smug Snake than Kagakagari.
And now, presenting THE CLUB PRESIDENT in episode 20. Yeah, killing Shuri, Yo, and Tomoharu-1. And his reason is that he wants the Hagane just to live in a world where his girlfriend is. Could have done a Kill 'em All if it wasn't for a minor complication.
