"Thanks." Su Yang thanked her.
He took her phone, intending to open the phone number, but suddenly paused.
"What's wrong?" Big Sister asked, watching him.
"...Nothing." Su Yang kept calm.
But that wasn't true.
He saw two numbers in the contacts.
One was labeled Home.
It was the number for the house.
But Su Yang knew the other number by heart.
He possessed powerful analytical, deductive, and interpretive abilities. Abilities such as photographic memory were something he genuinely possessed.
And this number was very familiar. He had called it before using the Puppet Technique.
Because this was...
Murasame Reion's phone number.
It was labeled Mio.
"Big Sister, is your name Hyakka?" Su Yang added.
"So you know." Hyakka nodded. "Faint thunder beneath an overcast sky. If only the rain would come, perhaps you would stay here. You've studied this poem from the Manyoshu, right?"
But Su Yang's attention was not on her.
Instead, he had confirmed something.
Murasame Reion really had been lying.
Before meeting Mai-senpai, he had never believed there were supernatural things in this world.
Nor had he believed that Murasame Reion was a Spirit like in the Original work.
But Kurumi's disappearance without a trace, followed by this...
It could now be confirmed.
Spirits really existed.
So Murasame Reion truly was the first Spirit, and Tokisaki Kurumi had most likely been captured by her.
The reason was quite clear.
It was to revive her old friend—the woman before him named Hyakka.
After becoming a Spirit, Kurumi had gained the power to travel through time.
But Hyakka, whom she had hoped to find and meet through time travel, was now standing right in front of Su Yang.
Then could Hyakka be used to restrain Mio?
It was worth trying.
"I just remembered that I can't memorize phone numbers..."
