"MC" is a go:

• Name: Yamamoto Momoko
• Age: 16
• Gender: Female
• Appearance:
• Personality: Momoko is a generally nice, quiet girl, and certainly not outgoing. She's quite self conscious about her bust and has a distinct fear of thunderstorms. On the other hand, she's a big fan of good food, rabbits, and doing the the right thing even if it's problematic.
• Abilities: Momoko possesses a truly enormous amount of Es--far more than is normal even for an Evoker, sufficient to allow drawback-free utilisation of a complete relic. However, she doesn't knowingly possess anything that could take advantage of it... or know that she has anything other than a normal level in the first place. She does, however, happen to be in possession of Ascalon--not a shard, the whole weapon.
• Skills: Momoko is a pretty average student, all things considered, but somewhat better at history and worse at English. Despite living on her own, Momoko's cooking is frankly appalling--not to the extent of burning rice, but if she wants anything to taste good (and she certainly does) it ends up being pre-packaged. The one subject that Momoko could be considered 'good' at is PE.
• History: Ten years ago, Momoko was on a day out with her parents. Ten years ago, she saw her mother put Ascalon to use against the Inverse--and despite the number saved, lost both her parents in the carnage. Though she still owns Ascalon, Momoko has no ability to recognise it for what it is or much recollection of her mother's actions at the time.
  Since then she was raised in a fairly hands-off manner by a family friend, living essentially on her own with occasional visits in a too-big house for one schoolgirl, in a part of Aoyama unchanged in decades. Fortunately, her parents had considerable savings and some investments, so she's not too badly off for the foreseeable future.

Name: Arima Rika
Age: Appears to be 17; possiby not wholly accurate
Gender: Female
Appearance:
Personality: Cheerfully sadistic and willing to antagonise for fun, Rika seems to be nothing more than a villainous monster that loves to taunt her victims - or flirt. Whichever gets the best reaction out of them. She makes no secret of her nature as an Inversed, and even plays up these aspects of herself, yet the humans she feeds from are, oddly enough, generally less than innocent.

In a strange twist, she seems to have a soft spot for kids and especially animals, often fawning over and even protecting them.

One thing that seems to irritate Rika is sympathy. Any attempts to understand her actions or potential methods tend to be met with rather chilly warnings, if you're lucky. In her own words, she is nothing more than a villain seeking ruin for all, and is not someone worth sympathising with.

Abilities: As an Inversed, Rika is able to consume Es, and also play with time in almost any way she pleases; time freeze, time alter, summoning herself from the past... just about the only thing she seems incapable of is time travel. She can even recover damage by reversing her own time. Rika is also immune to damage from mundane weaponry, thanks to her Inverse Barrier.

Skills: Rika's gotten pretty good at irritating people with a few sly remarks, and is an excellent babysitter.

Equipment: N/A
