Also known as: セミナー(ブルーアーカイブ), 研讨会, セミナー
Seminar is the Student Council for the Millennium Science School in Blue Archive.
The group originally began as a team of researchers attempting to solve the seven "Millennium Problems" that would eventually give their school its name. Eventually, as the scope of their project crept outward and into other areas of research, Millennium was founded and Seminar has taken a place as its executive committee.
Being a faction tag, this should only be used when all members of the group are present and equally in focus.
