Lol, when I first discovered KAITO, I looked him up on the vocaloid wiki and it đã đưa ý kiến he has no certain age, but is drawn bởi 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
xin chào there! Kaito has no official age. He was released on the first VOCALOID engine where age, weight, and height where not được trao for the first Crypton VOCALOID's (Kaito and Meiko). But, những người hâm mộ 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 bạn 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 tình yêu song. Luka is 20 and Miku is 16. It would make sense for Kaito to be in between them, sense ACUTE is a tình yêu song.
