The stage play "Souga" is a Sengoku period action-historical drama featuring Masaya Matsukaze, who played Mega Blue / Shun Namiki in "Denji Sentai Megaranger," and Ryota Murai, who played Yusuke Onodera / Kamen Rider Kuuga in "Kamen Rider Decade," along with Eiki Kitamura, who played a heartbreaking lover in the music video for Tohoshinki's "Lovin'you," Kento Ono, who appeared in MAY'S "I LOVE YOU ga Ienakute," and other unique performers such as Takeshi Yoshioka, who recently announced his marriage to Ai from FLIP-FLAP, and Macchan from Canary Club. The play centers around the Shiina family, who possess the strategist Tsumugi, known as the "strongest shield," and the warrior Ouka, known as the "strongest spear." They are threatened by the forces of the "Demon King" Genshu's army. The Shiina family, who had chosen to surrender in order to seek a peaceful resolution, are attacked by Genshu's large army on the day the castle is to be handed over. The two, separated, will become enemies, crossing blades with each other, each carrying their own sense of justice and feelings.
