This tag desperately needs clarification, I can tell just by scrolling it is being misuesed. Perhaps it needs to be purged, the correct tag created (Sensei (Blue archive) and then it can be reseeded properly?

Literally me

Would change to: "Japanese word for teacher. Commonly used for the protagonist of the game "Blue Archive."" Is all this tag actually only blue archive sensei? Then the description shoulde be if that is the case, something like... "Name used for the protagonist of the game "Blue Archive." Meaning the japanese word for teacher." Also, if all of the tag is actually blue archive sensei, the tag should be changed to "Sensei (Blue archive)" to be more clear.
