Lindon, Yerin, and Mercy Advance to Underlord

In the Akura vault within Night Wheel Valley, Lindon, Yerin, and Mercy each advance to Underlord while battling Seishen Daji and Meira. Mercy defeats Daji with shadow techniques, Yerin overwhelms Meira using the Endless Sword, and Lindon arrives as an Underlord to turn the tide.

Outcome

Akura Charity appears and awards the Blackflame Empire victory, but immediately separates Lindon from Yerin and Mercy by taking him to train with the Akura clan.
