24/7 surveillance
Reinforced sliding doors
No sharp objects permitted inside the cell
One (1) enrichment item rotation every 72 hours (approved: cat plushies, potato chips)
Personnel Level 2 and above may interact with SCP-XXXX-JP under the following rules:
1. Maintain a calm tone.
2. Do not stand with your back turned for more than 3 seconds.
3. Provide potato chips or cat-themed enrichment before interviews to reduce hostile behavior.

Description:
SCP-XXXX-JP is a 16-year-old Japanese male identified as Sylent Nabkhn, height 178 cm (5'10"), weighing about 45 KG's (99.21 pounds) with black eyes and medium-length black hair resembling the fictional hairstyle “Itoshi Rin.”
SCP-XXXX-JP displays:
Extreme movement speed (appearing to “blink” or “skip frames”)
Enhanced reflexes far above human limits
Unusual tolerance for pain
Compulsive predatory behavior, especially toward isolated individuals
Behavioral duality: alternating between calm, quiet observation and sudden calculated aggression
Strong positive response to cats and potato chips, which significantly lowers hostility
SCP-XXXX-JP typically uses small knives, improvised objects, or bare hands when attacking, though interviews suggest this is done out of “preference,” not limitation.
Despite violent tendencies, SCP-XXXX-JP displays violence or silly quirks, including:
Speaking to surveillance cameras as if they were pets
Following researchers silently for several seconds “just to see if they notice”
Loves cat
Tortures a doll
SCP-XXXX-JP claims to have been “born cursed,” and considers its violent impulses “fun.”

Addendum XXXX-JP-1 — Speed Analysis
High-speed cameras recorded SCP-XXXX-JP moving 9 meters in 0.12 seconds without generating typical physical indicators such as wind displacement or footstep sound.
Researchers note the effect resembles “imperfect teleportation,” though SCP-XXXX-JP insists:
“I don’t teleport. I just move better than you.”

Addendum XXXX-JP-2 — Shibuya Origin
When asked about Shibuya, SCP-XXXX-JP becomes noticeably more intense.
It describes the district as “home,” “training grounds,” and “the place that made me fun.”
Further details remain unclear due to SCP-XXXX-JP’s evasiveness and tendency to redirect with humor or threats.
—-
Addendum XXXX-JP-3 — Behavioral Stabilizers
Approved list of items that calm SCP-XXXX-JP:
Potato chips (any flavor except cheese)
Cat videos
Plush cats
Real cats (Level-4 approval required)
