"Gunjyo" is the first single release in about a year since the simultaneous release of "Hana" and "Shiori", the first nationwide release of TITLE UNTITLED. The title track "Gunjyo" was written by Hiroki Aoba, who also wrote "Hana" and has supported Titled Yet Undecided since its early days, and is a song suitable for spring that looks back on a year of running with dedication and expresses the "determination" of the girls as they gradually grow into adults. On May 20 (Mon.), they are scheduled to hold their largest-ever solo live "TETRAPOD" at Zepp DiverCityTokyo, aiming to transcend their base in Hokkaido and their genre as idols.
