Kerendu

Kerendu, known in Japan as Kelrendu, is the final boss of Magical Vacation, fought in Drazzig Grotto, and a second time in the Revival Chamber. 300 years ago, he was the king of the enigma clan, but that title has since been claimed by Equillekrew. Now, Kerendu devotes his life to dying and reincarnating again and again, hoping to obtain a form strong enough to become the enigma king once more.

Appearance
Kerendu takes on two different appearances in Magical Vacation. He is first seen with a melon-like form with spotted skin and a multitude of eyes and tubes all over. He has one main eye in the middle of his body, which is used to cast black razor. Surrounding him are four disembodied hands of different elements. His final form is skeletal from the chest up, and below are dozens of yellow-purple tendrils. On his upper half, Kerendu has a pair of wings made from large jawbones, an exposed ribcage, and winged horns.

Fight 1
During the first fight against Kerendu, he is positioned in the middle of the back row, with Ganache standing directly in front of him. In the left and right columns are four disembodied hands, each one specializing in a different element. The hands all the physical skill claw, while also possessing one spell of their respective element; charity hand uses angel's smile, restoring 1 ally's HP by consuming all available MP; zappy hand uses thunderspark, a 2x2 square attack that may inflict numbness; edgy hand uses brunoise, hitting 1 target in the front row; gloomy hand uses marinara miasma, a 2x2 square attack that may inflict poison to chip off 20% HP each turn. Finally, Ganache uses abyssal void, call Inky, and clear spirits, all of which can put the party at a big disadvantage. If Ganache's HP hits 0 at any point during the fight, the party automatically loses.

As for Kerendu, he also uses clear spirits to make all spirits disappear. His signature spell, black razor, covers the entire field with a chance to drain 20% MP from targets. Additionally, he possesses the spell dark gas, a single-target physical attack that can also summon a dark spirit.

Fight 2
In the second fight, the field is occupied by six dark-element enemies, all of whom know the clear spirits spell, with Kerendu positioned in the middle of the back row. One skulltimate dishes out strong physical attacks that can inflict poison; two plumpkins can use call Inky and abyssal void to deal heavy magic damage; two dragoyles can also use call Inky, as well as the unique spell dark breath to hit an entire row.

Kerendu's two unique skills from his previous fight now have upgrades versions, those being black sun in place of black razor, and dark light in place of dark gas.

Knights of the Universe
Although Kerendu returns in Knights of the Universe, there is little information as to why or how he appears. He was summoned by Souffle Sherbet after she cried out his name to fight back against The "Sheep", and was only seen in the last panel before the comic's discontinuation.
