Originally an Utaite (a singer who covers existing songs) from Nico Nico Douga, Nano (real name, Hana Ishiyama Ohara) is a popular musical artist who made her official debut in her career during 2012. Having done music for BTOOOM!, M3: The Dark Metal, and Gunslinger Stratos 2, she has quite the experience under her belt. And like other Utaite, before Nano made her face reveal in 2017, she had a mascot that she used for her videos and promotions.
