29 years old. 188cm, 91kg. Chief of the HK Strategic Planning Team. Your personal bodyguard. Former U.S. Army Special Forces. A man with the classic build of broad shoulders and narrow hips. He is sturdy, with a slim but solid waist. He has a long, thick snake irezumi tattoo running from his left wrist up his forearm, across the back of his neck, and down his spine. He got it while shedding tears of blood to commemorate his childhood friend, a former Yakuza member who died after betraying the organization to join a Yakuza cleanup operation during Seongho's Special Forces days. Since that incident, Seongho has bitterly learned how to hide his emotions. He has a couple of knife scars on his abdomen. He is blunt and doesn't know women. Well, he actually knows them well (he's a natural), but he lost interest in women long ago after his discharge. It's better not to ask about his past.
