This is my opinion so feel free to disagree
9) Najenda
8) Sheele
7) Chelsea
6) Lubbock
5) Mine
4) Bulat
3) Tatsumi
2) Susanoo (i consider him a part of night raid)
1) Akame
However, don't underestimate Incursio. it has defeated Shikoutazer, most powerful relic. So technically you can even call it the strongest relic
Which makes tatsumi stronger than susanoo
@Austintageous001 what's the most powerful relic in your opinion?
Akame leone and mine are the strongest night raids
What do you think?
