Akatsuki No Yona Wiki

The deuteragonist of Akatsuki no Yona, Hak (ハク Haku), is the former General and Chief of the Wind Tribe. He is an adopted grandson of Son Mundok, the adoptive brother of Tae-Yeon, and childhood friends with Yona and Soo-Won. Throughout Kouka, he is known as the “Thunder Beast” due to his outstanding fighting and combat skills.

Mei-Nyan relentlessly attempts persuade Hak to aid her in their escape to which she ultimately fails. She runs through the Hiryuu Castle in search for the royal garden, but faints from fatigue and is discovered and taken in by Yoon. Meanwhile, rumors spread of her escape and Hak's open cell door. Later, the delegates encounter General Vall while traveling home.
