Why do I have characters at Lv 240 or higher?

Raising 5 characters in your roster to Lv 240 will strengthen Level Link.
From that point on, it will become possible to raise the Lv of characters set in Level Link slots to Lv 240 or higher. However, for characters that have an initial rarity of N or R with a max Lv of 240 or lower, their Lv will not be able to be raised beyond their max Lv via Level Link.

Furthermore, the max Lv a character with an initial rarity of R can reach after using Awaken Unlock is tied to their current rarity, and cannot exceed their corresponding max Lv.

・SSR＋ or lower: 160​
・UR: 180​
・UR+: 200​
・LR or higher: 240
