My SSS-Rank Dragon Bodyguard

My SSS-Rank Dragon Bodyguard is a fantasy short drama about a princess everyone in Valeria dismisses as weak, until a legendary dragon answers her call. Evelyn has no magic and can barely walk any distance, yet when her father is captured and her sister is gravely injured, a storm dragon missing for seven years descends and kneels before her as its king. A royal sorcerer craves that bond for himself while an army of twenty thousand closes in, and Evelyn faces it all without ever casting a spell. The series runs 23 episodes in total.
