(POV - Lia)
I'm Lisanatoa Kazuya. 17 years old. An elf. Even though I'm serious and intelligent girl archetype, I'm still a maiden in love. That's plain embarrassing to admit. Cool down, calm face. I will tour his sister around the school so maybe I can her favor… W-wait, what's with that cold gaze sister-san? Or should I say sister-in-law-san? Her gaze becomes colder!
"Class Rep?"(Shin)
"Ahh, yes. Let's start the tour."(Lia)
"Okay, Shira, let's go."(Shin)
"Uhmm, may I go with you too?"(Yumina)
"Yumina-san?"(Lia)
A third wheeler huh… Well, it can't be helped. I know she also likes Shin-kun. Same to Rin-san. What can't be monopolized should be shared. Sometimes, Japan's laws are so inconvenient in times like this. Wait, if we married in Astral Plane, it'll be fine. But, no normal humans can travel there… I continue the tour until Shira-san requested something.
"Onii-chan, can you buy us the limited edition ice cream at the cafeteria?"(Shira)
He made a dubious face.
"W-we're in he rooftop y'know?!"(Shin)
"Please."(Shira)
She revealed an earnest expression. He sighed and nodded.
"Money?"(Shira)
"No need. I'm not richer than you but I'm still rich."(Shin)
"Huh? What is onii-chan saying?"(Shira)
After he left, Yumina-san spoke.
"You're truly his sister. You knew he can't refuse an earnest request."(Yumina)
"Indeed."(Lia)
She just smiled. Then she return to her usual serious expression.
"Do you like, no, Do you love onii-sama?"(Shira)
[Wh-!!!](2)
What a direct question?!
Realizing our feelings, she continued.
"My brother was burden by many things. And in the future, he will be burdened by much more. I don't know if I can support him with the weight he will carry. Can you stay with him forever even the end will come?"(Shira)
We resolutely nod.
"I already betted everything in this feeling."(Yumina)
"It's the same for me."(Lia)
Then, her face turns flat.
========
Divine Possession. An ability to let soul of the god dwell in the body of the mortal. It is usually used for combat. Her letting the deity speak means her Holy Magic is Level 10 along with Oracle skill. The deity uses her body to pose like the idols at the stage. She doesn't plan to take over completely right?
"Of course I won't. She is my great great…great grandchild yes?"
She gave us her divine protection.
"Don't tell anyone what happened okay?"(Amaterasu)
[Yes.](2)
She sighed, annoyed.
"Geez!! I don't want to do more work but those two stupid archangels really!! Making our jobs harder than it usually hard!!!"(Amaterasu)
She cheerfully said goodbye while murmuring about asking the other pantheons
about the situation.
(POV - Shira)
Obaa-chan is really unreasonable…
"Are you alright?"(Lia)
I nodded with a bitter smile on my face.
"Perhaps you're conscious, Shira-dono?"(Yumina)
"Yes."(Shira)
It is just a half-way possession so I never been asleep. I have the control so I let
obaa-chan do what she wants.
"I'm quite tired."(Shira)
I sleep on the bench while sitting.
(POV - Lia)
"Really, this girl" (Lia)
"Fufu, I got approved by the sister, fufu" (Yumina)
"Now that you mention it" (Lia)
So sister-in-law-san approved it huh, with also a seal of her grandma.
"Yumina-san, Lia-san, what happened to my imouto?" (Shin)
"She just fell asleep. Also, just call me Yumi." (Yumina)
"A-also call m-me Lia desu!" (Lia)
Kyaa! I also said it! Shin-kun awkwardly said our pet names.
