I just made my very own UTAUloid. His name is Hourousha Kashikoi-oto. Here's the readme file so you'll know about him and the rules in advance.
Name: Kashikoi-oto Hourousha (賢い音ホウロウシャ)
Meaning: Smart sound of the Adventurous
Birthday: May 15
Favorite Colors: Green and Blue
Character Items: Rice Ball, a microphone he calls Star Mike, a star-shaped guitar he calls Big Lead, a sword he calls Uta Ken (歌権)
Personality: He's not only a UTAUloid, he's a good swordsman and a very smart guy. He can also be very adventourus. He's usually a serious person, but he can be calm sometimes. When he not singing or adventuring, he is known to study quite often. He will protect his friends when they need it. He doesn't do dirty and he's straight.
His voicebank is encoded with romaji with some hiragana aliases, so locales won't be a problem.
If you want to make the best of him, follow these guidelines.
