Len Kagamine is a VIRTUAL SINGER who watches over the various SEKAIs: School, Stage, Street, Wonderland, and Empty. In all SEKAIs (except Empty), Len takes on the personality of a high-spirited teenage boy with a love for music and performing. In the Stage SEKAI he is slightly more mature and collected, and in the Street SEKAI he has much more of a desire to prove himself and not be seen as a little kid. In the Empty SEKAI, Len is a young, nervous boy who is unsure of himself.

Voice: Len has an energetic and loud medium-high pitched voice, that differs slightly depending on which SEKAI he is in. Due to Len being a teenage boy, him being voiced by a woman is entirely plausible and might make more sense (ex: Bennett from Genshin Impact).

Note: By voicing Len, your vocals will be slightly altered to sound more robotic. You will also be taking on the responsibility of voicing several male and/or female NPCs, as the VIRTUAL SINGERs (besides Miku) are the least prominent characters. If vocal alteration makes you uncomfortable, or you'd rather not voice multiple characters, do not audition for him.
