Humanoid Monster Bella Episode 0

Umenokisaka Bella comes to the class of Ohno Shiori as a transfer student. The classmates are interested in Bella's looks but she doesn't respond to them at all. Angry with her attitude, they decide to bully her.

The next day, Shiori is shocked to see that Bella, who fell from the rooftop in front of her, is fine. Ayane is forced by Kaoru and Rin to steal in a downtown area at night but Bella appears before her.

Rin hides her secret social media account from everyone, but that doesn't stop her from obsessing over the number of followers her account has. After the numbers drop, she gets desperate to increase them.

Rin manages to recover her number of followers but is outed as the owner of the account. She is shunned but sticks to the account regardless.

Nanami, an idol, is given a lot of affection by her mother. However, she is in love with her manager and wants to retire. She goes to Shiori to help her plan selling the story to a weekly magazine.

Nanami's plans get crushed and she is forced to drop out of school. Shiori is convinced that her classmates were involved in the death of Kozue.
