These characters are not as powerful as the SS rank tier but do all have a place on most teams. These characters are mostly ranked S due to their Ninjustu which can become very useful for different events.
Note:
Haku can be pulled only at 5 star. Kabuto and Shikamaru can be pulled at 4 or 5 star but 5 star is recommended.
Tier A characters are good units as you will be limited to your team pick due to team cost. These are over shadowed by the tiers above but will have units very similar with lower stats and more cut down abilities.
Note:
Neji, Tayuya, and Sakura can be pulled at 5 star and that is recommended. Shizune can be pulled at 4 star and that is recommended.
