[u][b]Masters[/b][/u]:
[list][*][u][b]Name[/b][/u]: Honda Ami
[*][u][b]Age[/b][/u]: 17
[*][u][b]Gender[/b][/u]: Female
[*][u][b]Appearance[/b][/u]: [url=https://i.imgur.com/abXkLXv.png]She's a long way from home.[/url]
[*][u][b]Personality[/b][/u]: "Too serious" might be a good way to start describing her. Approaching things carefully and with due consideration, not making lots of jokes or goofing around... it's no surprise that until recently, Ami was the sort of person that had absolutely no belief in the supernatural, trusting only the things that she could directly measure. It's a worldview that has taken something of a dent for obvious reasons.
[*][u][b]Skills[/b][/u]: Being a Japanese schoolgirl, Ami doesn't bring much in the way of useful skills to a Grail War--she's sort of okay at taking care of herself and not starving to death, and she's okay at schoolwork, but in a battle to the death...? Well, she could be [i]more[/i] helpless--she knows how to swing a sword perfectly adequately--but having practised for the purpose of sports (and particularly demonstrations) is quite a far cry from cutting through a person.
[*][u][b]Abilities[/b][/u]: For a start, Ami isn't a magus. This isn't to say that she doesn't have magic circuits, it's quite likely that she [i]does[/i], but they've never been used and she doesn't know the first thing about magecraft. Instead, what gives her the ability to compete within a Grail War is being a once-in-a-lifetime prodigy born with the correct manner of breathing--her very physical existence connecting herself with the world. Harnessed, it would give her some immensely powerful abilities...
But paired with someone unaware of said talent and previously sceptical of the very existence of the supernatural?
There isn't all that much that she can do with it, though the situation that Ami has found herself forced into has lead to [i]some[/i] hasty interest. It's forced her to push her physical limits--at her peak, she can keep up with the church's murderers despite having no training for such, being just a schoolgirl from a normal life. Almost everything else Ami can do is linked to her prior refutation of the supernatural: she can cut spirits as easily as if they're flesh ("it's just someone dressing up"), is extremely resistant to magic or enchantment herself ("it's just a trick of the light"), and cut through or disable magical barriers the same, ("why has someone scratched nonsense onto this rock?"). Though with her mind opening to the concept, it's tempting to try and see if some techniques that she thought only existed in anime are possible...
Amusingly, her greatest achievement, in entering into the war, was entirely by taking part in a game to "summon" something as a joke. Already selected by the Grail--and unaware of the command seals--she instead called a Servant to her... one that, due to the strange nature of the summoning, doesn't take mana to remain summoned, as Ami is instead the interference keeping the Servant in place. The downside is that she has no ability to supply mana for the use of Noble Phantasms...
[*][u][b]Brief Backstory[/b][/u]: Apart from her colouration, there is nothing interesting to say about Ami's early life except that she grew up in a town that had quite recently had a [i]massive conflagration[/i] occur--though she wasn't from the same area at all, so it never really factored into things. She grew up, went to school, started doing mostly iaido... her talents slipping completely under the radar of any magus that might take an interest--though, to be fair, there weren't many around and they were preoccupied with something completely different.
Yet just two months earlier, Ami relented and agreed to try some mass-market occult nonsense with her friends. Normally, there was no way that this would have done anything, even with her talents. Yet the light bruising on her back showed that the Grail had already picked her as a candidate--and when she put the effort in to try and summon, [i]something[/i] answered--which quite probably would also have not happened were she not in Fuyuki at the time, even with the grail elsewhere.
This, naturally, caused problems. Summoning a Servant of any description, especially with witnesses, is hard enough to keep under wraps. But learning how dangerous it is and the associated risks... that people might come to somewhere as unremarkable as Fuyuki from America just to kill her off--and possibly her family--meant that staying here and trying to find someone that could help just wasn't an option. Ami would [i]have[/i] to go and take part for her parents' and siblings' sake.
They probably aren't too happy about her running away from home that way, though. At least the Servant part helped with getting the sword along to the USA with her.
[*][u][b]Assets[/b][/u]: None. Finding somewhere to stay is actually her first priority.[/list]
