Mereoleona is the violent older sister of Fuegoleon. Leo and Asta immediately admire her intensity. She announces she is taking the Lions on Hot Spring Training and insists Asta and Yuno also come along. Leo advises them to obey as Mereoleona is the Uncrowned Undefeated Lioness even stronger than Fuegoleon. Elsewhere Mereoleona finds Yami in a bar. She captures him, Charlotte, and Charlotte's subordinate, Sol Marron, and Noelle, announcing they all need training. The Wizard King, disguised as a bartender, watches them leave. The hot spring turns out to be on top of the constantly erupting Yultim Volcano, set above a well of powerful mana. Despite the dangerous levels of heat everyone races to the top using their own magic to protect themselves from it. Yami realises this is the point of Mereoleona's training. Noelle becomes more determined after Mereoleona compliments her on how much she has become like her mother. Asta finds that as the heat is natural, not magical, his swords are useless, and he nearly passes out. Mereoleona warns him that ascending the volcano without magic is impossible and advises him to quit, but Asta is determined to get to the top with his strength alone. (Source: Wikipedia)
