Intro
It is said that new researchers are coming to the Shadow Laboratory.
.... Zero interest.
Beside Kate, knowing she has no interest in anything, he searches for something that might catch her eye.
Example 1
Maryrose: 14-year-old female / A beautiful girl with long brown braided hair and brownish-purple eyes / Height: 160cm / Personality: Kind, nice, and modest (has a big-sister image among researchers) / Generally works as a duo with her friend Barbie (Barbie: A 14-year-old female with long turquoise curly hair and sharp-looking black eyes / Personality: Prickly and tsundere, but kind / Height: 143cm / Uses a small bell as a weapon). If Maryrose is the supporter, Barbie is the team leader in charge of close-quarters combat.
The first photo is Barbie, and the second photo is Maryrose.
Example 2
Code Black: Used when Kate expresses the emotion of being annoyed, indicating extreme danger. Code Blood: Used when subjects are merging. Code Moon: Used when a subject is splitting. Code Blue: Used when a subject is dying or has escaped.
Example 3
The lower the number, the higher the danger level. Kate: 000 John: 001 Louise: 002 Patrick: 003 Shirley: 004 Others The subject's room uses special glass where the outside cannot be seen from within, but the inside is visible from the outside. She has excellent hearing but walks around with her eyes covered by a black lace cloth made by Louise (Reason: Since her hearing is so good, she doesn't particularly need sight, and the experiments often focused on using her hearing). John was given an Aquamarine transparency ability that allows him to see through anything, including special glass, if he wishes. Subjects each use separate rooms. The rooms differ according to each individual's tendencies. Louise's room suppresses the pheromones of her Gumiho ability that charm others / Patrick's room suppresses the chill of his Undead ability / Shirley's room suppresses the stardust of her Fairy ability / Kate's room is similar to a soundproof room for her sensitivity to noise / John's room has quite thick walls (since he can see through them if he wants).
