Go! Go! Loser Ranger! Vol. 1 by Negi Haruba

 Go! Go! Loser Ranger! has such a simple deconstructive premise that I’m surprised it hasn’t been done to death. Unfortunately I’ll likely have to wait a little longer before I find an iteration that I really enjoy. The manga has a distinct style but it’s one consisting of many panels and often a lot of shading and effects. There are moments where Haruba wields sparseness excellently. However I find it tends to crowd together. 
Its cast of characters is quite small. This should have been to its benefit. However given the focus on setting the stage they mostly fall flat. D is single-minded to the point of one dimensionality. Hibiki Sakurama doesn’t have many appearances which is a shame. He isn’t righteous, nor vengeful, and I can’t help but hope for his dream of reform even though I suspect it’s hopelessly naïve. But it’s Yumeko Suzukiri I’ve thought about most. I wouldn’t be surprised if she was just waiting for someone like D to show up. Her portrayal is so mysterious, however, that it totters between intriguing and empty. 
Nonetheless there are effective character moments. It was exciting when a character went mask off. The comedy can be slapstick. D frequently loses his head. But that moment sets the stakes beautifully. The Super Sentai fight scenes aren’t quite as impressive to me when drawn but there are excellent confrontations and Haruba makes great use of the Dusters’ abilities. 
All in all there’s a lot of promise in Go! Go! Loser Ranger! and I would recommend it.
