In Tower of God season 2, episode #15, Bam’s Viole alter ego is at risk of being foiled by an old acquaintance, while Khun has some reunions of his own. The second season of Tower of God is a lengthier affair than season 1, with season 2’s characters pitted in a deadly dance against alumni of the 25th Bam’s first outing. The Workshop Battle is in full swing, with passage to the Archimedes locked behind a deadly game poised to seriously cull the herd of competitors hoping to reap the event’s rewards.
