Among the myriad of heroes, who will you choose first? (By looks is fine too!)

Hello Heroes! A lot of new information about the latest installment has been released, hasn't it? So, I wanted to ask everyone who seems to be the most popular so far. Choosing based on intuition and looks is also okay! Here's a summary of each protagonist, quoting the official descriptions: ① Kai (CV: Daiki Yamashita) A spirited and devoted boy who lived a 'normal' life with his father. The red jewel on his left hand is said to hold mysterious powers. He participates in the 'Grand Gladiatorial Festival' with his childhood friend to save his imprisoned father. ② Dietrich (CV: Satoshi Hino) A beautiful swordsman from the land of Fodra across the sea, who enjoys fighting for pleasure. He lacks humanity and believes only in himself. He is also a wielder of the 'Demon Sword Answerer' and participates in the 'Grand Gladiatorial Festival' seeking battles against stronger opponents. ③ Theodora (CV: Minami Takayama) The young queen of the Kingdom of Salamis. She possesses an unyielding will to face any hardship and the qualities of a ruler, and her right arm is said to be able to crush rocks with her bare hands. She participates in the 'Grand Gladiatorial Festival' to fulfill her homeland's centuries-old wish. ④ Leda (CV: Mariya Ise) A beautiful, top-class vihuela player who dedicates her entire life to revenge. She acts cheerful on the surface but carries an extremely deep darkness within. She participates in the Grand Gladiatorial Festival to take the life of the man who killed her father and restore his honor.
