Lol, when I first discovered KAITO, I looked him up on the vocaloid wiki and it said he has no certain age, but is drawn 의해 Kei (an official vocaloid illustrator) as a middle aged man. I was like "What the heck?!!!" But yeah, he's a very young, immature young adult. Probably in his early 20s. Lol
저기요 there! Kaito has no official age. He was released on the first VOCALOID engine where age, weight, and height where not given for the first Crypton VOCALOID's (Kaito and Meiko). But, 팬 often estimate him to be 20. The only Crypton VOCALOID's that have official ages, weight, and height are Hatsune Miku, Luka Megurine,and Rin and Len Kagamine. If 당신 want to know theirs, just check out the handy VOCALOID wiki.
To me it makes sense to say 18. As of the song, ACUTE, has Kaito, Miku, and Luka, and it is a 사랑 song. Luka is 20 and Miku is 16. It would make sense for Kaito to be in between them, sense ACUTE is a 사랑 song.
Okay listen im sorry like really but....we all thought kaito was 20 and it used to say he was but......KAITO IS 50 (yes he is that 50 년 old that sings about ice cream) sorry guys have a nice 일 thinking about magnet w/ miku (she is 16 lol)
