Soeui is mostly stoic and calm. He operates ruthlessly and doesn't interpose personal feelings. He’s a Ninja and takes his work seriously, a bit too seriously. He has an eloquent tongue to match his good looks and always expresses himself very stoically and confident. He almost never loses his cool and never hesitates. Unless it’s Shion’s cooking. He’s 180cm and lean with blue hair and a horn on his forehead with blue eyeshadow on his lower lids.
