Lemon is a second-year junior high school student. She is a PriMagi otaku who is very knowledgeable about it. Her preferred brand is Radiant Abyss. She is extremely shy and tends to get nervous quite easily. Whenever someone gets too close to her, her soul/ectoplasm starts to come out from her mouth, but only magicians can see it. Because of her shyness, the words she speaks may come off as rude to others. However, when it comes to gaming, she is much more outgoing and casual, and she is able to talk normally.
