Glutamine

Glutamine (ぐるたみん) is a popular with a nasal voice who sings with much passion and energy.

Some of his most famous traits are mumbling where he forgets lyrics, screaming, and adding catchy sequences during instrumentals, such as in his "Panda Hero" cover. His voice displays an energetic variety, with a range of noises, tones and emotion.

His singing power and range can be seen in his covers of both "Matryoshka", and "IMITATION BLACK", where he also solos three roles; smooth and sexy, loud and energetic, and even shota. However, as shown in his covers like "Rokuchounen to Ichiya Monogatari" and "Shinkai Shoujo", he can sing in a very quiet, serious, and even a sad tone bordering a whisper.

He can also be somewhat silly. For example, in his collaboration cover "Bad ∞ End ∞ Night", he imitates 's role, giving the song a humorous twist.

His most popular cover is his "only my railgun", which has over 8.6 million views as of April 2017.
