Can you legally name your school anime club Genshiken?

Yes, you can legally name your school anime club "Genshiken," but it's important to consider trademark issues. "Genshiken" is the title of a popular manga and anime series, and using it as a club name could potentially lead to confusion or claims of infringement, especially if the club engages in activities directly related to the series. To minimize legal risks, it's advisable to clarify that the club is not officially affiliated with the original work and consider seeking permission from the rights holders if necessary.
