Go! Go! Loser Ranger! 4

Attention kaiju and sentai fans! From the creator of The Quintessential Quintuplets comes a new "anti-ranger" action-comedy that'll make you root for the alien invaders! Perfect for fans of Kaiju No. 8 and Power Rangers.

After having infiltrated the Ranger Force in the guise of trainee Hibiki Sakurama, D must pass the final exam for promotion into a real squadron, or he’ll never gain access to his true goal, the Dragon Keepers. However, the test seems impossible: the candidates must retrieve a key from their assigned examiner, but the examiners’ power is overwhelming! If they could work together, they might stand a chance, but they soon discover there’s only a single “key” per team, and quickly turn on each other! Meanwhile, deep in the shadows, a monster boss thought long destroyed is making a move… Will D be able to survive this battle royale?

Negi Haruba debuted in 2013 with the story "Coward's Crossword" in Kodansha's Magazine Special. Haruba's first series was Purgatory Karma in 2014, followed in 2017 by The Quintessetial Quintuplets, which became a runaway hit worldwide and inspired two seasons of anime and a film.
