The God of Desolation Ran Away with an Angel

Question: What's it like to have a little sister who's been your childhood friend?

Thanks for asking. I'm in the Slum, and when I open my eyes, there's an unconscious girl beside me who looks like a nonhuman: the kind with a halo over her head and wings growing out of it. Wait! I think she's waking up!

Angel: "Avatar."

Young Chuuya: She's so close to me. She must be the little buddy I knew from the lab before I lost my memory!

Special Division for Unusual Powers: ??? Our spy went through so much to infiltrate that mysterious organization. We were supposed to get the person out, so why did we come back with just the files?

Dark Era Dazai, holding the script: Where's my slug? Where's my huge slug?

Ordinary, unremarkable Mori Ougai: !!! This is the real angel!

The world's greatest detective: Ah, those two ran off ages ago.

Dark Era Dazai: ?

Mori Ougai: ?

Special Division for Unusual Powers: ?

When Chuuya first woke up, a young girl was lying beside him. She had short, pale blue hair, white wings at her ears, and an angelic halo glowing above her head. Her pale purple eyes had no pupils. She weakly tugged at his arm and said, "Avatar."

At first, he thought the word had some special meaning. Later, he learned that "Avatar" was the only thing she could say.

Special Division for Unusual Powers: Sure, we got our person stolen, but we can always get her back.

Mori Ougai: With an ability like that, it wouldn't be surprising if she really were an angel.

Chuuya: Yeah! Avatar is an angel! (Blushing as he hugs her tightly.)

Avatar: ?

A certain Foundation doctor whose name starts with B: Get a grip, everyone! This is a Keter-class containment object that can chat and laugh with 682 and 049, for crying out loud!!!

1. A one-on-one, sweet Chuuya romance with an everyday-life feel.

2. The heroine is an original containment object, fragile, and an all-purpose healer.

3. A short story, so it won't be too long.

4. Character design for the cover is in progress.

5. OOC warning! I'm a newbie who hasn't written many stories, and I'm still working on my writing. Please bear with me.

6. I'm writing this for love, and none of my stories are paid. Feel free to drop the story or leave a negative rating, but I'll moderate negative comments in the comments section, qwq.

Theme: A childhood friend can heal any emotional wound!!
