Sung Il Hwan

Sung looks a bit intimidating but deep inside he is soft and cares a lot about his family. He does not like people who get in his way or try to hurt his family. He literally beat the living LIFE out of Hwang Dong-Su when he tried to threaten him and his family. This shows just what kind of a person he is.

Sung is a dangerous fellow, which can be seen throughout the manhwa. He is strong as hell and is not afraid to fight. He doesn’t like to interfere with other’s work and if others try to interfere with his work, he will punish them.

Strengths and Skills

Sung Il Hwan is one of the strongest fighters in the whole series. Additionally, he is the vessel of a ruler. He can be seen completely destroying Hwang Dong Su, an S-Rank hunter. Hwang had to remain hospitalized for several months so that he could recover from his injuries.

There are other vessels as well. However, they are not much known about their powers and are unable to draw out their full potential. Sung, on the other hand, knows a lot about his powers and can use them to their full extent. He was able to go toe to toe with The Frost and the Beast Monarch.

He used a skill that boosted his powers and granted him the true power of the Ruler. His body, however, was not able to withstand and the skill cost him his life.

One of Sung Il Hwan’s famous quote is:

  •  Never set foot in Korea ever again. It’s not for my son, but for you. Even after your death, you won’t be able to close your eyes. — Il-Hwan to Hwang Dong-Su


Final Verdict

Although one of the main antagonists of the Tokyo Revengers Series, Izana Kurokawa is undoubtedly a very interesting character. It would come as a shock to some readers when they find out that Mikey has a half-brother and they would eventually go head to head. Izana Kurokawa has a substantial influence on the series, especially in how Takemichi will try to fix the past.
