The Secret of the Eye of the Midnight Sun

Asta and the others safely return to the Black Bulls' base after defeating the Eye of the Midnight Sun and the Diamond Kingdom in the Witches' Forest. Now that Asta's arms have healed, the Black Bulls as well as Yuno, Klaus, and Mimosa are relieved. However, there's no telling when the Eye of the Midnight Sun or the Diamond Kingdom will try to attack the Clover Kingdom again. Klaus then brings up a proposal to Yuno and Mimosa.
