"Flags” are certain phrases or events that set up (and are believed by some) to cause later particular outcomes.

You can find out what happens next!

Could it be→Flag-chan?!


Originally used as a computer programming term to indicate a variable for conditional branching, analogous to the branching of the direction of travel using the international signal flag system (a series of universal flags used for communication among ships at sea, with various meanings).

Often used in its verb form, "fla****g". Its use as "flag" could be said to be a notational quirk, giving the word a different meaning.

Flags in programming

A kind of variable, used when you want branch processing based on whether or not an event is occurring or has an attribute.
Since there are only two ways to do this: with or without a flag, the data size only needs to be 1 bit per flag.

Flag as a slang term

Refers to a situation in which an event implies a subsequent event.
Since flags are only expressed from a meta perspective, there is often no causal or correlation between an event and subsequent events. For example, the line "Once this war is over, we're getting married" is a typical example of a death flag, but there is no causal relationship between this statement and death. When there is a relationship, it is often referred to as foreshadowing.

In computer games, flags are used to branch the development, and the term "flag" has come into common usage, especially via otome games.

The types include death flag, survival flag, loss flag, and many others, but when a game is tagged simply with "flag", it indicates not only that but also the beginning of a romance flag.
Semantically, it is similar to "foreshadowing".

Thinking “because A happened, B is sure to follow,” is a cliched trope, because one can somewhat predict what will happen next. ...But that's okay.

When people say "that's a flag" or "I got a flag" in daily conversation, either in the real world or online, they are almost always referring to a death flag (and also to failure, defeat, and other equivalent meanings).

However, the meaning of a flag in program terminology differs from that of a flag derived from the program terminology and used in general. The former is set to 0 or 1 at the moment an event occurs, while the latter is expressed as "flagged" when an event is about to occur. Therefore, the flag is raised before the event occurs. The flag may be 0.1, 0.5, or in accordance with quantum mechanics, 0 and 1 may overlap.
Of course, there are no such concepts as "strong flags" or "weak flags" in the programming terminology of flags.
