The official website for the upcoming fourth television anime adaptation of the Teekyu manga series and its spin-off series Takamiya Nasuno Desu! has announced that both shows will premiere in Japan on April 6, 2015.

Millepensee is producing the fourth season of Teekyu instead of MAPPA, but Shin Itagaki returns as director. All four of the main voice cast also reprise their roles.
