V Singer Noodle Stopper PVC Statue Luo Tianyi Fallen Angel Ver. 14 cm

According to her short anime series, Luo Tianyi is an angel who came to earth with a mission to spread music to the world. Tianyi can detect "the song of your heart"(心中的歌声) of a person. The "Song" can be interpreted as the strongest emotion a person has at the moment, or a melody that represents them. Even if the person cannot express the melody themselves, Tianyi can still hear it and sing it.

Her personality is a bit introvert, but she is still the type of girl who has a lot of empathy and does not give up easily. She admires the VOCALOIDs from the past, and dreams of the day she can do just the same as them – using songs to bring happiness to the world. While she cannot communicate with humans due to the language barrier between humans and VOCALOIDs, she is very sensitive to others' emotions and can use songs to express her own emotions and thoughts.

Her special skill is "Resonate" (共鸣).
