"Kirigiri-chan, aren’t you happy? You’re at rank '2', there’s just a little bit left to reach your goal of rank zero."

"That’s just a transition point."

"As expected." I said with a shrug. "Since it’s a transition point, what about after that? Do you plan to continue increasing all digits to zeros and become a Triple-Zero rank?"
'0' is the sign of the highest level. If one continues in accumulating merit, all three digits will become '0', and they will be called a Triple-Zero rank.

In the past, there were only a few people in the Triple-Zero rank, and each of them was a super-special detective that went far beyond the norm.

'The Count of the Armchair' – Ryūzōji Gekka.

'The Law Enforcement Officer' – Johnny Arp.

Identity Unknown 'GHOST IN THE MIRROR' – Mikagami Rei.

They all passed by us and went away at a frightening speed. The battles with them were so detached from reality that in retrospect it even make me wonder if it was just a dream.

...I wonder if Lico is having a good time in America right now.

"One '0' is enough, I don’t need more."

"Why? Is it because it's too conspicuous? Speaking of which, detectives of the Kirigiri family can’t stand out, right?"

"Not for that reason. Registering in the Detective Library is not something a detective from the Kirigiri family should do, but there is one thing I have to do regardless."

"And what's that?"

I asked, and she started weighing her words, and after a moment of silence she continued:

"…A farewell." she said, looking down. "For that I need to get into Hope's Peak Academy. That school has a scouting system, and if you
don’t have a strong background, they won’t even look at you. In that sense, the Detective Library's numbers are just a simple and effective index."

"Oh, so you... intend to go to Hope’s Peak Academy."
