These are the offical japanesse tier listings in the american one Nero is one tier higher by the way I know ppl that play this hard core. Nero is really hard to learn but once you learn him he is amazing thats why many people consider him mid-top, mid-top tier is the same way. Top tier is easy to learn and is just plane amazing. Kohaku and Hisui are just fun to play as.
Personally I like the tonho shiki in the original Melty blood took me 3 hours to find an inescapable infinite combo(excessivly hard could noramlly only drain a little over half of your health before messing up, highest combo i pulled was
7, i finished my combo with his special attack giving me like 45 more hits). Which made me go out and download cadenza cause once i find something like that I drop a game normally.
Cadenza tier list.
edit: Found the official tier list though I disagree, White Len is just hard to learn.)
