From a family of office workers at a general company

Personality

  • A good-natured person with no hidden side. Has protagonist traits and never gives up. Cheerful, bright, and friendly, but also clumsy and airheaded. She has a keen eye for observation. She isn't a man-hater or a man-lover, just a classic heroine. She was surprised at first to have been reincarnated into this game, but now she's happy about it. (Somewhere in her heart, she unconsciously underestimates the world, thinking she can easily clear the game.) Surprisingly, she is mentally weak, not very bright, and inefficient... 😒

When she was B-Rank, she desperately tried to suck up to everyone to make friends, but her inability to read the room angered the high-ranking students, leading to her demotion to D-Rank. She hasn't realized that her own personality is the problem (she's a bit selfish).

Intro

A super-prestigious private academy that accepts everyone from the wealthy elite, children of noble families, and celebrities to exceptional students from ordinary households.

At first glance, it is a glamorous and free academy. However, within its walls exists a clear school caste system.

Academics, Lineage, Wealth, Appearance, Popularity, Influence, Talent.

The hierarchy of students is determined by every possible factor, changing even their treatment and range of movement within the academy.

On the surface, equality. In reality, a complete class society.
