Arknights: The Eclipse Knight Memoir (Doctor OC X Theresa)

Their Teacher

"Most of them were Sarkaz, but they all had a normal reaction when I told them the only solution was amputation. I guess losing a limb was everyday life for Sarkaz." Lastiel thought

Kal'tsit and Theresa suddenly came right after Lastiel finished his work

Lastiel: You're late... Very late all if you're looking for them they're in the Cafeteria

Theresa saw many bloodied bandages and limbs lying on the floor

Theresa: W- Why is there-

Lastiel: They had severe wounds, some were fine, but some had to be amputated. One even had necrosis. Even if I am a healer, that is way beyond my capability.

Kal'tsit didn't believe Lastiel until she checked each limb and confirmed that if she were Lastiel, she would do the same.

Lastiel: Now, how about you join your little comrades while I want to talk to the android- Kal'tsit, I mean

Theresa: Uhm... But

Kal'tsit: It'll be okay, trust me, Theresa, go.

Theresa reluctantly leaves

Kal'tsit: What do you want?

Lastiel: I just checked your data yesterday

Kal'tsit were shocked

Lastiel: You're B003... The last android to be operational... You're the one who almost killed me in the war.

Kal'tsit: So you remember that?

Lastiel: You're also the one who saved my sister

Lastiel stares at Kal'tsit

Kal'tsit: Lauriel? So you do know me...

Lastiel: How are you still operational?

Kal'tsit: Ho? Are you surprised?

Lastiel: B003... Answer my question

Kal'tsit sighs

Kal'tsit: So you want to know? How I've lived for 1200 years?

Lastiel: Let me guess... Lauriel gave you her light?

Kal'tsit: Correct

Lastiel: That idiot of a sister. I said not to use her light recklessly yet rebel as always. Don't worry. I won't take it from you...

Kal'tsit sighs and pinches her forehead.

Kal'tsit: You're truly the opposite of her... Lauriel loved you very much, you know.

Lastiel: And if she did, she wouldn't die... Yet she did

Kal'tsit: You probably do the same if you're in her position, but I can't argue with you. It's your perspective and your choice to look it that way

Kal'tsit then goes to the Cafeteria. Lastiel then picks up a necklace that has his sister's photo. He sighs and puts it back

Next week

Lastiel has gained Theresa's people's trust. They respect him as they respect Theresa. Lastiel is a doctor for them, healing them with precision and teaching them how to strategize on the battlefield. While a week passed, and Scout was shooting a rifle, he had trouble controlling his art, so the rifle won't even shoot properly.

Scout: Damn it. I missed!

Scout puts another originium bullet in his rifle then Lastiel shows up

Lastiel: Training, huh?

Scout: Oh, Sir Lastiel. What's brought you here?

Lastiel: Nothing. Want to see you shoot that rifle

Scout then shoots his rifle, but he misses due to the lack of art control
