Go! Go! Loser Ranger! manga volume 14 features story and art by Negi Haruba, the creator of The Quintessential Quintuplets.

Green Squadron is making a comeback! By working together, Chidori, Hisui, Angel, and D manage to back Deathmecia into a corner and are one step away from victory when suddenly, the boss monster sleeping inside Angel awakens. The tables appear to have turned, and it all seems hopeless against the clearly invincible Deathmecia. Green Squadron is all out of tricks--or are they? Someway, somehow, it's time for the three-way melee to come to an end.
