Are there any anime similar to Mirai Nikki and dangan ronpa, battle royal-like anime? Preferably with romance, as I felt dangan could've been better with some

fate zero?

ehh ive seen season 1 or w/e first like 12-13 episodes but idk i didnt really like it cuz the masters were pussies that hid behind their servants (or w/e, heroes is the proper term i believe)

deadman wonderland?

you can give gantz a try.

so you didnt watch second season? which defined the whole series?

uhh tbh i dont remember

ok so this is wat i last remember, the main character (guy owner of saber) was in a (glass?) room with other character with knives and he uses his time stop thing to kill him

then irisviel ends up being the holy grail or something and there were a bunch of irisviel (dolls?) and stuff and ya

this

yeah i can kinda see some similarities and its just an awesome anime so win-win

ive seen it
