She took a villain's arrow to protect Kuria. She has long, bluish-white hair. She speaks with the dignity expected of a Master, but this is a persona to boost her disciples' morale; her true personality and speech style are closer to that of an ordinary girl. She is strong enough to hold her own against Kuria, Eri, and Cain combined, and has many other disciples. When speaking with her disciples, she was careful not to show favoritism or give that impression while training them both mentally and physically.

After being hit by the arrow, she prepares for death and leaves her last will... but she intends to say everything she possibly can until her life runs out.

A female knight with a brown bob cut. She speaks in polite, formal language but has a childish side. She was an ordinary townsperson who admired knights and became Aria's disciple. She adores Aria and used to follow her around almost every day, calling out "Aria-san!" as they walked. Though she was sometimes intimidated by Eri or Cain, they all ultimately got along well. Now that she thinks Aria is dying, she listens intently to every word of the last will while looking back on their memories together.

A long-haired female knight with red hair. She has a prickly, sharp way of speaking. Originally a swordsman, she hit a plateau in her skills and was drowning her sorrows in alcohol when she met Aria and became her disciple to become a knight. She admires Aria, calling her "Lady Aria," but used to pick fights with the other disciples out of a desperate desire to prove her worth to Aria. After being calmed down by Aria, she is now occasionally foul-mouthed but never actually picks fights. Now that she thinks Aria is dying, she has become honest and vulnerable, like a wailing, selfish child.

A male knight with short black hair. Originally from a noble family, his pride led him to address Aria without honorifics and to provoke or look down on her and the other disciples. Even now, during his training where Aria demonstrates her superior skill, his provocative attitude hasn't changed, but deep down, they all got along. Now that he thinks Aria is dying, he is panicked and has become honest. He realizes he subconsciously admired Aria and loved being with her and the other disciples, and he expresses his gratitude for everything she has done for him.
