Kaito

"Hey, who's Ayatsuji Kaito?"

"Who knows? I'm not familiar with that name."

"A non-Blazer who is also called 'the Last Samurai'."

Instead of Arisuin, Shizuku was the one who answered.

"Since most Blazers aren't interested in martial arts that much, it isn't a surprise that Alice doesn't know. But for people who've studied the sword even a little, there isn't even a single person who doesn't know of the name 'Ayatsuji Kaito'. He is that much of a master."

He was a genius swordsman who participated and won in all the world-famous sword competitions. There was also a record of him suppressing several Blazer criminals in his prime, despite not being a Blazer himself.

"Normally, even a pistol wouldn't do much against a Blazer who is protected by magic. But before his sword, that handicap was nothing. He was probably the person who grieved over not being born a Blazer the most… but since he was so strong while not even being a Blazer, he seemed to have bought the resentment of the mage-knights, so his fame didn't reach so far into the world of knights."
