Problem Solver 68 is one of the clubs at Gehenna Academy in Blue Archive.
A club notable for taking "fixer contracts" and conducting other illegal business. Its members are usually on the run from the Prefect Team, and sometimes even the Justice Task Force.
The number 68 is believed to be derived from the first two characters (陸八) of Aru's family name, Rikuhachima (陸八魔).
Being a faction tag, this should only be used when all members of the group are present and equally in focus.
