Please spell his name right, it's Kaito and not Katio. I don't hate Miku, but I don't like her either. It's just neutral for her. I absolutely love Kaito. Fell in love for "Kaito ga Uninstall" because I imagine his character as a really cheerful guy who is actually sad inside but he never shows it. I'm not voting for Kaito not because I'm one of those haters who're like "why do people like her so much? Since she's so popular, I'm going to differ my answer to sound unique." It's really sad that he's the second-to-first made Vocaloid but isn't very popular compared to Miku who is actually the third Vocaloid but is named the 1st. (Her number is on her right/left(can't remember) shoulder, not really but on her arm near her should.) Kaito mostly never plays the bad role, but even when he does, he has a good side to him. For example Judgement of Corruption, even though he judges for money no matter if the client is good or bad, he's doing for his non-existent daughter. Even though the daughter he's doing all of this for doesn't really exist, it doesn't change the fact that he's doing all these bad deeds for her. I kind of think he's one of those underrated characters. He is kind of popular right now but not really.
