Clea is a secret boss found in the Flying Manor. This area is located on a floating land at the center of the map and can only be reached once you Esquie regains the ability to fly.
You will need to defeat the first four bosses in the Flying Manor to unlock the room where Clea is. Once all four are defeated, speak to the Young Boy in the middle of the glass cases and proceed to the door. Choose to push through the door's warnings and face Clea.

Clea's attacks revolve around summoning previously-fought enemies, such as the Dualliste or the Bourgeon, to hit the party. These enemies appear for her attacks, and are chained together for complicated combos.
Each of Clea's attacks starts with her gathering Chroma, which heals her for around 600,000 HP if not interrupted. You can only stop her from recovering a large amount of HP by parrying every single hit from her attacks and performing a counter.
Taking even a single hit from Clea or dodging will invalidate the counter and not stop her from healing. Parrying all the attacks becomes important to prevent this and dispel the protective Chroma defending Clea.
One way to bypass Clea's complicated boss fight is to defeat her in one hit. This can require specialized builds, but will trivialize Clea's fight.
It is recommended to try Maelle supported by Sciel, and set Maelle up to have her Stendhal ability one-shot Clea.

Sciel's main job in this set-up is to apply both Marked to Clea and Fortune's Fury on Maelle. Make sure that Sciel is the first in the turn order by removing everyone except Sciel from the party, then adding Maelle back in. This will make Sciel attack first before Maelle, with both attacking before Clea thanks to First Strike

Maelle should act directly after Sciel. Have Maelle use Last Chance to regain her AP, then follow this up with a perfectly-timed Stendhal for maximum damage. This should be enough to one-hit Clea.
Maelle Best Builds and Attributes
Clea summons powerful Nevrons for a single-target 3-hit attack. There is a slight delay before each attack, as each summoned Nevron winds up slightly before striking.
Clea summons violent Nevrons to hit the whole party 7 times. For the first six attacks, alternate between parrying the Chalier and jumping the Stalact attacks, then parry the final Stalact hit.
Clea summons musical Nevrons for a string of 5 attacks on a single character. There will be four slashes, followed by the pair of Troubadours going in for a fifth hit.
Clea summons creepy Nevrons, calling on them to do a 4-hit attack on a single character. The first three Nevron attacks have similar parry timings, and the fourth Hexga hit is slightly delayed.
Clea summons agile Nevrons to attack a single target 6 times. The first four hits come in quick succession, while the latter two have some slight delay before they land.
Clea summons tricky Nevrons for a 6-hit attack on one party member. There are four quick attacks, followed by a delayed attack that you have to jump over, and one more delayed attack for the sixth hit.
Clea summons Nevrons from the deep, attacking a single team member 5 times. The combo consists of a quick two-hit attack, followed by another quick double hit, and ends with a slow Bourgeon slam attack.

You can outdamage the heal with tier 3 gradient attacks, the real annoying part is her summoning the bourgeon that eats one of your party members, they won't get spit out even on breaking her.

She is also weak to ice damage. You can one-shot her in normal way with Maelle and 3rd gradient attack + barrier breaker, since it deals void damage.
