Turns out Mars is more than just a very gifted mage. He is, allegedly, a result of Diamond Kingdom's human experiment and became their secret weapon. Yuno cannot defeat him alone, is it time to give teamwork a chance?

Summary
The moment Lotus realizes that Asta had managed to cause extensive damage on him, he decides to escape along with the rest of his subordinates. Asta tries to pursue him but fails and Rack Boltia suggests that they should return to their original objective of conquering the dungeon. Subsequently, he notices that the strongest person in the dungeon is actually someone else.

In front of the door connecting to the center of the dungeon, the fight between the Golden Dawn members and Mars from the Diamond Kingdom continues. Klaus Lunette who is still unable to fathom the gap of magical power between Yuno and Mars, notices the stones embedded on Mars' forehead. The stones remind him of the rumor surrounding the Diamond Kingdom regarding their research on creating strong mages. He begins to feel disgust over the Kingdom's inhuman treatment over their mages in their pursue of strong warriors, which he suspects that Mars is the result of it. Subsequently, he also feels dejected over his own helplessness in the situation and decides to attack Mars. However, Mars easily counters it by creating a body clone composed of crystal in which is strong enough to hold Klaus. Mars also immediately continues his assaults at Yuno with the latter is struggling to evade while counterattacking at the same time. Yuno's attack becomes even more useless when Mars covered himself in a crystal-based armor while telling Yuno to surrender.

As the fight continues, Yuno begins to remember his training session with Asta when they were young in which leads to his refusal to admit defeat to Mars. Being a merciless person, Mars continues to pressure Yuno until Asta comes in and stops him by cutting Mars' sword with his own. Asta and Yuno then prepares to resume the fight while Rack and Noelle Silva also arrive at the scene.
