Read Manhwa Only I Have an EX-Grade Summon online in English. Also known as I Alone Am an EX-Class Summoner, Solo EX-Rank Summoner, and 나 혼자 EX급 소환수.

Baek Jinwoo spent years buried in Battle of Summoners, a punishing game where creatures are ranked from weak F-class familiars to elite S-class monsters. After reaching the top of the Tower of Trials, a traffic accident leaves him in a coma. When he finally opens his eyes three years later, the game he knew too well has become reality, and the world now runs on summons, systems, and dungeon-like trials.

Everyone is chasing power through familiar rankings, but Jinwoo carries something no ordinary player can match: ten years of hard-earned game knowledge and a summon that breaks the rules completely. With an EX-grade creature at his side, his once-wasted obsession may become the key to surviving a transformed world.

This series may appeal to readers who enjoy summoner fantasy, game-system action, and tower-climbing growth stories.
