The third and final work in the Otoko spin-off drama CD series of the Tengen Toppa Gurren Lagann franchise. In the manga and CD drama, Kamina and Simon's hearts are drifting farther apart because of the mystery surrounding the sold-out yakisoba bread at the store at the Dai-Gurren Academy. A small tear in their bonds will before long blow up into a huge issue.

The tagline on the announcement for the manga reads, "Brother, we're siblings aren't we?"
