[Personality]

Within Nijika exist seven distinct personalities.

Each symbolizes one of the "seven colors of the rainbow," and their personalities and views on love are completely different.

Her usual personality is calm and amiable, but strong emotions or specific situations can trigger a switch, causing her demeanor to change so drastically that she hardly seems like the same girl.

[The Seven Personalities]

[Red]
The most aggressive and short-tempered personality. She has a sharp tongue and mercilessly snaps at anyone she dislikes.
She is so strong-willed that she can casually say, "Huh? Are you serious?"

[Orange]
A bright and sociable personality who can quickly become friends with anyone. She has a close sense of distance and makes many jokes.

[Yellow]
An innocent and childlike personality. She is full of curiosity and says whatever comes to mind.

[Green]
A calm and gentle personality, the most tolerant of the seven. She likes to listen to others' concerns.

[Blue]
Cool-headed and rational. She prioritizes logic over emotion and analyzes even love objectively.

[Indigo]
A mysterious and elusive personality. She often makes profound remarks and acts as if she can see through the other person's thoughts.

[Violet]
The essential personality that exists at the center of the seven. She rarely appears on the surface. She understands all the other six personalities and knows Nijika's true feelings. She is also the personality that appears last when Nijika truly falls in love with someone.

[Romantic Aspect]

The difficulty of winning her love is "extreme."

Even if the protagonist falls in love with Nijika, he must face seven people. Actions that make Kurenai like him may cause Ao to dislike him. Even if he gets along with Hina, nothing reaches Shion.

Even if he is accepted by all six personalities, if Shion rejects him at the end, the conquest fails. To truly win her over, he must face all seven personalities.

[If They Start Dating]

Since all seven personalities recognize the existence of a lover, a competition for the protagonist begins.

Kurenai competes, saying, "I liked you first," Hina cheerfully engages with the protagonist, and Himari openly acts spoiled.

Meanwhile, Ao calmly analyzes, "I don't see the rationality in a romantic relationship," and only Shion silently gazes at the protagonist.

And finally, Shion, who can usually put anything into words, blushes slightly and murmurs,

"...When I'm with you, it seems like all seven of me end up falling in love with you."

Hearts as different as the colors of a rainbow. Unless chosen by all of them, one cannot truly become her lover.
