He Just Became the King of Ruin and Was Summoned by the Powerful School Beauty.

Traveling to the Shadow Island of Runeterra, he became the ruined king Foyego who could control the soul and the black mist. He has to face all the heroes in Runeterra. When he first comes up, he has to fight Senna and Lucian, who are known as the model couple of the Sentinels of Light. Fortunately, he has awakened the Curse of Destruction system. As long as he collects Isulde's soul essence, he can become stronger. He originally thought he would dominate the entire Runeterra, but unexpectedly he was summoned by someone from another world who signed an ancient contract. ... I am Su Qingxue, the school beauty from the orphanage. During the talent awakening ceremony, I awakened the SSS level talent Ancient Contract Summoning. I thought I could summon some powerful ancient race, but it turned out to be just... A human? I gradually realized that I seemed to have fallen in love with him, but in his heart he only had the woman named 'Isulde'. "Foyego, I am willing to hand over the last of Isolde's spirit in my body and let me be your Isolde for one day, okay?" This novel and its characters are purely fictitious.
