It's a comprehensive comic, but it's a pity that I didn't follow the serialization. The sisters who followed the serialization single-handedly made the protagonist almost single.
It's a comprehensive comic that even people who don't know anything about virtual singers (such as myself) can watch it. The inhumanity of the robot is well written.
Original treasure article! Why do so few people watch it? The setting is very interesting, the foreshadowing is also very detailed, and the ending is recycled!
