After Shizuki and Mitsuru come to encourage her to stop Takuma, Tamaki embraces him and finally awakens as the Tamayori Princess to calm him down. After attempting to stop Eins from hurting Takuma, Tamaki summons the Onikirimaru from within the lake, breaking the barrier which covers the area in a dark breeze.
