Band-aid

This character wears a band-aid.

Band-aid is a small dressing used for injuries not serious enough to require a full-size bandage.

It also can be used as an accessory in order to look sloppy, tough or dangerous.

Note: Only used this tag if the character actually has a band-aid on for a length of time or shown wearing it.
For example, do NOT use this tag, if a character accidentally cuts his/her finger, puts a band-aid on the wound and then the visual novel immediately cuts to the next scene, never mentioning or showing the band-aid again.
