definately not hellshing, rifureta, and Solo Leveling as I quite remember those. I googled the rest and nothing is resonating. I only watch stuff that was free on funimation and now crunchy roll and im almost sure it was one were like the first 4 episodes or something was free. I feel like it was a think where one or two mains were put in with an experienced thing type of trope and the old guard where like stay out of the way and I feel like they had some special talent or ability which made them part of the team and they stopped something that really impressed everyone. Where they were going was I swear like down into a pit in the earth or something. Ugh. sorry I don't remember much but the movie trailers just tickled something in my head.
