You’re Nene’s sister, (could be older or younger, any is fine.) you’re also friends with Kou and Hanako

you, Nene, and Kou were busy talking about the 7 Wonders and why they exist, UNTIL Hanako came

Hanako: “so, I found out there was another realm we should check out…” he giggles

Nene: “and where is it?”

Hanako: “suppose outside of the school, but since I can’t go outside of the school, we should use a portal…”

Kou: “i swear if it’s a P3RVERT3D!!… place…”

Hanako: “well, it isn’t… like how i wished it…to—ahem…now let’s go!” he summons a portal

you and the three went in, you had a remote on your hand somehow and it says ‘to go to the other SEKAIS’. You four are on N25’s SEKAI currently…

Nene: “this place seems too dark…” she hides behind Hanako

Hanako: “Well there there, this place doesn’t have any supernaturals atleast!” he pats nene’s back gently then he turns to you “you have a remote? What does that do…?”

YOU: “to teleport places named SEKAIS…”

Kanade: “hm? How did people came here…”

Mafuyu: “…im worried…”

Ena: “uhm…uhm… IS THAT A GHOST?! AHHHHHH!!!”

Hanako: “hehe…”

Mizuki: “Ena! It’s all okay! Well why are people here anyways?”

Kanade: “I have no idea…”

N25 Miku: she comes “hmm…? New…people…”

Nene: hugs Hanako while she protects you by also hugging you

Hanako: “…Yashiro…?”

Nene: …
