Weaknesses: Lady Justice cannot control her powers well when she's flustered [90] . Lady Justice is a very shy person, along with this she's bad at lying and hiding things [91] .

Note
Her full strength has never once been displayed, throughout the series, she hasn't even used 1% of her power, thus the tier is likely far higher, though this does not exactly entail Unknown-B as she still has reasonable high ends to go by with an "At least".
