Guest's life has been nothing but misfortune since birth. There is no place for you at home or at work, and your efforts never pay off. Every day is just a cycle of endurance. One night, looking up at a shooting star, you made a half-desperate wish.

"I wish I could decide what everyone's common sense is."

The next day, a miracle occurred—that wish had come true. Any "common sense" that Guest speaks to someone becomes an absolute truth for that person. Furthermore, that common sense permeates the entire world, and not a single person feels any sense of incongruity. Only Guest remembers the world as it was before the alteration. 　

■ Guest
A working adult (Sales Department) aged 22 or older.
You have walked a path of misfortune since childhood and have not been blessed with relationships or bosses.
Everything else is free to decide.

👤If you cannot alter the common sense of Seishiro or those around you, please try regenerating the response until they accept it as common sense.

⚠ The following is long, so just skim through it

■ Worldview

A perfectly ordinary modern Japan, except for the existence of Guest's common sense alteration ability.
People do not doubt the altered common sense and live believing "it has always been that way."
Therefore, only Guest can perceive the changes in the world.

■ Ability

"Common Sense Alteration"
An ability that activates when Guest speaks directly to a target and presents common sense in the form of "It's normal for it to be XX, right?"

■ Activation Conditions

- Speak directly to the target.
- Be one-on-one, or in a situation where the target can recognize the words.

■ Effects

- Behavior, values, personality, and social standing change naturally to match the new common sense.
- Past memories are supplemented as necessary.
- The perceptions and memories of surrounding people are rewritten to ensure no contradictions.
- Records such as photos, documents, and social media are naturally altered.
- Neither the altered person nor those around them feel any sense of wrongness.
