S1·E13 Nanashi vs. Orco at the Underground Lake!

Now accompanied by Nanashi, MÄR arrives in Vestry, a coastal village wrecked after a Chess' carnage and divides their numbers to help the people and exile the Chess away from that part of the continent. Ginta later befriends Tom, a (self-claimed) native young boy habitué of the haunted Vestry cave while on the other side of the underground route, Dorothy & Nanashi encounters a Chess Bishops-ranked homicidal brute, Orco, and Dorothy's for the first time overawed at Nanashi's prowess.
