I watched Gungrave and the first episode of "A certain scientific railgun" (To Aru Kagaku no Railgun)
And here are my thoughts:
-Its animation really looked a lot like Trigun! Regarding the gray colored monsters (I think they were called orgmen if I remember correctly), what are they? Are they genetically enhanced or were they just made out of nowhere?
-Although the 1st ep was intriguing, I think the backstory was a bit too early. It would’ve been better to have more action in the present timeline than starting with Brandon’s backstory early into the series.
To Aru Kagaku no Railgun
-First episode’s minimal yet surprising power demonstrations got me hooked instantly! It also explained a lot about the title. hahaha
-I think it would do great even without the fan service but, well, I don’t think the creator would settle for it.
-Misaka’s so cute despite the strong front she’s constantly putting up. haha
Again, thanks for those who gave their recommendations. I'm currently enjoying the animes you've suggested
