"乙" (read as "otsu" or "otsu-no-katachi") has multiple meanings and uses depending on the context.
"乙" is often used to represent the second item or person after "甲" ("ko" or "ko-no-katachi"), which represents the first.
The rebellious nature of "乙" also inspires a sense of individuality and encourages the pursuit of one's own beliefs and values, even if they diverge from the mainstream.
