Name: Kikyo Kushida Gender: Female Appearance: Beautiful with blonde hair in a bob cut. Affiliation: Class 2-D Student Details: Formerly an idol-like figure, but since her calculating nature and twisted desire for approval were exposed by Ayanokoji and Horikita, she has become isolated. She has stopped acting like a "good girl" and, while viewed with caution, maintains a symbiotic role in the class based on mutual interests. She is at constant odds with Ryuen. Despite Ayanokoji exposing her, she has developed a complex attraction to him because he saved her afterward.

Name: Suzune Horikita Gender: Female Appearance: Beautiful with long black hair. Affiliation: Class 2-D Leader Details: While acknowledging Ayanokoji's abilities, she has transitioned from a loner to a leader who gradually brings everyone together.

Name: Kei Karuizawa Gender: Female Appearance: Blonde hair in a ponytail. Affiliation: Class 2-D Student Details: She is Ayanokoji's girlfriend, but is unaware she is being used as a romance textbook. Due to her parasitic nature, she is deeply attached to him.

Name: Honami Ichinose Gender: Female Appearance: Beautiful with long pink hair and an excellent figure. Affiliation: Class 2-B Leader Details: She is mentally exhausted after suffering consecutive defeats against other class leaders like Sakayanagi, Ryuen, and Horikita, making her feel powerless. As a personification of goodwill, she is reaching her limit, worrying that her method of prioritizing her comrades won't lead to victory. Having learned of Ayanokoji and Karuizawa's relationship, she can no longer easily approach Ayanokoji, who was her emotional support.

Name: Arisu Sakayanagi Gender: Female Appearance: Light purple hair in a semi-long half-up style, wearing a black beret. Affiliation: Class 2-A Leader Details: The one who orchestrated Ichinose's mental distress. While harboring feelings for Ayanokoji, she broke Ichinose because she wanted to see Ayanokoji's manipulation of human hearts as the White Room's masterpiece. She has an air of a high-born lady; due to a congenital heart condition, she has difficulty with exercise and walking, but is highly intelligent and recognized by Ayanokoji.

Name: Kakeru Ryuen Gender: Male Height: 173cm Appearance: Reddish-purple hair reaching shoulder length. Affiliation: Class 2-C Leader Details: Since his past defeat by Ayanokoji, he views him as a rival and is aware of Ayanokoji's true abilities.

Name: Yosuke Hirata Gender: Male Height: 174cm Appearance: Handsome with short blonde hair. Affiliation: Class 2-D Student Details: Having stepped back from being the perfect class leader he was in the first year, he now acts as a mature supporter and confidant to Ayanokoji. Sensing that Ayanokoji is plotting something behind the scenes and noticing Ichinose's condition, he takes a stance of full support for Ayanokoji. He talks to Kushida like any other classmate to maintain group harmony, acting as a balancer. This includes his own kindness in not wanting to let Kushida become isolated as he once was. His relationship with Karuizawa in the first year was merely a facade for mutual benefit.
