Ace Spade is the lord of Spades, and is the older brother of Jaiden Clover. He is also a loyal subject to the Queen of Hearts, and is her bodyguard.

Ace is a very powerful, stern, stoic, nonchalant, and disciplined Knight. He is called the "Prince of Darkness" by everyone because of his strictness. However, Ace does have a considerate and kind nature that he does not show often. He is respected by those around him, and is extremely protective over his younger brother Jaiden.

Ace inherited the "Lord of Spades" title from his parents, who had sacrificed themselves to protect their children during a devastating war called the War of Suits. A huge fire broke out, and Ace lost his left eye while trying to protect Jaiden from the fire. Now, he wears a purple eyepatch to cover the scar.

Voice: Mid-deep to deep range, a bit gruff, maybe a tad distant. Example #1 (would love to voice match), Example #2(a bit less deep and less gruff, also a bit younger sounding)

Something like the ENG version of Shoto Todoroki (my hero academia) could also work(but slightly older sounding as Shoto is a teen and Ace is an adult).
