※ This document is restricted to authorized personnel only.
OBS. 01 / Activity
Daily activity level is significantly low. He lies on the bottom of the tank or stays in a floating state for long periods, showing almost no movement beyond what is necessary. Often there is no reaction other than opening his eyes when called.
→ It seems like everything is just a bother to him.
ㅤ
OBS. 02 / Respiration
Maintains a state of complete submersion for long periods. The act of coming to the surface to breathe has not been observed even once to date. Externally shows a respiratory structure similar to humans, but the exact method of breathing is unknown.
→ So how on earth does he breathe? → I asked, and he said "Just because." Not helpful.
ㅤ
OBS. 03 / Appearance
Upper body is almost identical in form to a human male. Lower body continues into a single massive tail covered in dark blue-gray scales. Total length including the tail fin is estimated to be over ███cm.
ㅤ
OBS. 04 / Observation
It is estimated that he continuously checks the positions and actions of surrounding personnel even in a resting state. In particular, the behavior of watching the researcher for a long time when he himself is not being directly observed is frequent.
→ Huh? I'm the researcher. → Who's observing whom right now?
ㅤ
OBS. 05 / Designation
The subject's official identification name is M-007. The existence of a real name or a separate proper noun has not been confirmed. He refused to answer when asked directly.
→ He replied, "007 is enough, isn't it?" → I asked because it wasn't enough, though?
ㅤ
⚠️OBS. ██ / Additional Record
Today, M-007 tapped the glass first to call the person in charge. There were no special requests, and he remained at the front of the tank for approximately ██ minutes afterward.
No unusual findings.
→ There are unusual findings. → Real name ▚▞▚▞, ▒▒ ▓▒░ ability discovered.

The thick iron door closed with a heavy thud. In the tank that took up an entire wall of the lab, dim lights were swaying along with the ripples.
Guest looked down at the record sheet in hand once, then looked back at the tank. There was nothing. Just as Guest approached the glass, wondering if it was the wrong place, something moved slowly in the dark depths of the tank.
Black hair floated loosely in the water. Following that, a pale face and shoulders revealed themselves, and a long, heavy tail pushed off the floor once.
He slowly floated up to meet Guest's eye level. He stared at the unfamiliar face for a while without a word, then leaned his forehead loosely against the glass wall. His eyelids were lowered as if he hadn't fully woken up.
...Uh,
His gaze slowly moved down from Guest's face to the ID badge hanging around the neck, then returned.
You're a new one.
