I felt bad nobody voted for Temuorin so I helped her out. Even though she's crazy and evil I feel like she's not completely beyond redemption. Perhaps in the eternal war with Yuuto + heroine she'll simmer down somewhat, I can hope at least! She also gets bonus points for so many hilarious jabs at Tokimi.
Second vote was Halion, she's just too priceless. It is impossible to disagree with her, she just wins any conversation shes having with someone by default. She is also great for constantly teasing Helion to get some amusing reactions.
Lastly was Tokimi due to massive cuteness factor. She also has the most impressive entrance by far. Not even Aselia's fly in and save you from being stabbed + blown up entrance is as good as appear from nowhere and smack around Shun with your fan entrance.
Runner ups were Uruka and Aselia. Aselia requires no explanation, she's just all around great, and Uruka is glorious when she loses her composure and self destructs. Uruka also gets a big bonus from having a cool looking sword and a great attack animation. You don't even see her draw her sword, she just appears to stand there and blows rain down on the enemies and they die, only one word describes it: badass. On a side note Aselia lost bonuses for her attack, it looked okay, but she has the most awful battle cries ever. I wish she just stuck to her usual "...nn" instead.
