Chapter 13

Mage of Diamond (ダイヤモンドの魔道士) is the 13th Page of Yūki Tabata's Black Clover.

Fights are finally taking place within the dungeon. However, which one got the tougher opponent and which fight would Asta and Noelle be involved in?

Summary
After defeating all of his target's subordinates, Luck Voltia subsequently challenges Lotus Whomalt to a fight. Uninterested on fighting, Lotus decides to escape before being outrun and being held at bay by Luck. The Diamond Kingdom's mage then begins to share a few reasons on his kingdom's constant invasion towards the Clover Kingdom, but is left talking to himself as Luck is only interested in fighting him. In another corner of the dungeon, Asta and Noelle Silva are still wandering the dungeon trying to find its center with Nero's direction as their only guidance.

As Luck clashes with Lotus, the latter begins to recollect his memories about the Black Bull squad and its captain. He remembers that Yami is the only opponent he could not defeat who is younger than him, which excites Luck even more. Suddenly, Luck loses his balance and his opponent reveals that he has been activating a spell that slowly weakens Luck overtime. Meanwhile, the Golden Dawn members arrive at the gate to the center of the dungeon. As they try to figure out a way to enter, someone attacks Mimosa Vermillion without her noticing, a feat that shocks Klaus Lunette because mana sensory is one of her specialties. As Klaus demands the attacker to show himself, the perpetrator walks towards them and orders the Golden Dawn members to step out of his way.

Lotus decides to let Luck weaken even further and leaves. However, as Luck is hearing voices inside his head, he dashes towards the man and demands the fight to continue.
