Important Note:

In this Tier List, we defined the strongest units as S+ Units and the lowest as C-Rank Units. We would like to inform you that the character list is based on the JP Version of the said game. Meaning some of the units here are already in the Global version.

Character names in the list might be changed as we roughly translate some that are included. We will try our best to revamp this list as the global version updates. We ranked the units depending on how we found it useful in the JP Version.
