①Ai’s relationship with B-komachi members can be found at ……

The protagonist, who was originally an idol as a member of B-Komachi, discovers an archive of videos of her live-streaming 16 years after Ai’s death. She disliked Ai; B-komachi was a group that explicitly favored Ai, and the other members were treated as back dancers. The protagonist also appreciated the charm and ability that Ai exuded, and understood that without her, the group would not have been successful. However, as he grew older, he became jealous of Ai, who was losing her shine, and he began to feel hatred toward her. His selfish recollections stand out, such as harassing Ai even though he was pulled by Ai and sold well, but considering the circumstances, perhaps he can’t be blamed. ……

②B-komachi members watching Ai’s delivery video

He says that Ai was always aloof and never really spoke his mind. The protagonist thinks back to the old Ai while watching Ai’s delivery videos. He is amazed at Ai’s beauty, which he has not seen in a long time, and recalls how secretive she was when he heard her answers to his questions. Ai’s smile, from the protagonist’s point of view, seemed expressionless. The protagonist thinks that Ai used to get into trouble when he hears her talking about her love life and saying that her type is someone who doesn’t get angry when she gets into trouble. As a former member, she recalled that Ai used to talk about how she didn’t recognize others or herself as individuals.

③What are the true intentions of the Eye and the protagonist?

The video feed is interrupted in the middle of the video, and the protagonist visits an unofficial blog that used to be run by the four initial members. The password is “45510,” the first letter of each member’s name, which was entered by flicking the numbers. There was only one article there that had not been made public. It’s a bit cryptic now, but I feel bad. I really want to get along like we used to. You can make fun of me more. It was an article written by Ai to the members, telling them that he was a member of the group. The main character closes the article in the middle and deletes the article itself. The expression on his face that he feels this is not the invincible Ai was completely that of a believer. Even though he hated Ai as a member of the same group, the main character was still fascinated by Ai as an idol.

What is your review of the novel “45510”?

 It was very satisfying to learn about the relationship between Ai and B Komachi, which was not well depicted in the manga. Knowing Ai’s true intentions makes her death even more sad. …… Ai really wanted to be friends with the members of B-komachi. Seeing that she didn’t change her phone password even after Aqua and Ruby were born, she must have always cared about the members.

In the original work, Ai had an image of being self-confident and cheerful, of being perfect and flawless. However, the atmosphere of the live delivery depicted in the novel is somewhat lacking, and Ai seems more human. Her final words of weakness and desire to make up with Ai are also surprisingly different from the image of Ai. I guess the main character was one of those who watched and searched for images of Ai, whom he hated, and was helplessly fascinated by her. ……

Consider why Ai cares so much about the members of B-Komachi.

While Ai has lived her life hating lies, she started working for the moment when lies become true and love is known. B-komachi was the first place she was given such a place. If you read the novel “45510,” you will see that the initial members of B-Komachi were close when it was first formed. From the fact that she really cared about the members, Ai must have felt a glimpse of “love” from the friends she made for the first time at that time. That is why she continued to have feelings for them even after they became less friendly.
