A few years later—

Mai and Rei had skipped ahead in grades, standing among the very top students of the Academy.

Rei’s goal of becoming the “chill king” meant constant study and training: politics, economics, mana control, emotional theory…

Mai, with her past life as a magical girl, drew so many questions in lectures that she practically needed her own assistant.

Naturally, the two had settled into the role of the Academy’s shining idols.

“Lady Mai, may I join you for lunch?”

“Lord Rei, I was moved by your essay on emotional dynamics!”

No matter where they went, cheers and stares followed.

But here was the problem.

“Mai… let’s have lunch together again today…”

“W-wait, Rei!? Again!? People are watching, could you back off a little!?”

His old “clingy phase” hadn’t faded with age—it had only evolved.

Now that he was nearly her height, his habit of silently shadowing Mai step-for-step had become so infamous that some students whispered it was one of the Academy’s Seven Mysteries.

Blushing furiously, Mai protested:

“S-stop… lately it’s just… too embarrassing, so cut it out already…!”

But Rei didn’t budge.

“…I love you. I want to be with you. Every day. Forever.”

Only when Mai looked ready to faint from the sheer pressure did others physically pull him away.

Meanwhile—

“Lorl-sensei… I need advice.”

In the guidance room, Rei spoke with unusual seriousness.

“That idea of ‘twin Demon Lords’… the truth is, Mai and I aren’t actually related by blood. So… doesn’t that mean I could marry her?”

“…Ohhh boy.”

Lorl promptly spat out his tea.

“Wow, that’s… heavy. I mean, technically it’s not impossible, but still…”

“I’m serious. If I want to stay with her forever, maybe I need a formal bond. A system that guarantees it.”

“…Yep. Definitely heavy. Your love has actual mass now.”

Rei’s devotion was no longer just an emotion.

It was a gravitational force.

Macikado Mai, age twelve.

Growing as a candidate for “chill king,” yet caught between her brother’s crushing love and the expectations of the world—

a turbulent page of adolescence.
