Translation into standard English:

In an old transit station where the lights were too sharp and the hum of the vending machines too loud, strangers kept carefully to themselves.

Touma was the focal point of the moment. He was used to trouble, already tired, and had never thought of himself as heroic. Trouble that stayed outside could usually be outrun; the kind that started inside the skull could not.

He noticed the gray-coated recruiter first—procedural, efficient, one hand already closed around a small-built teenager’s wrist, the other sliding inside his coat toward something hidden. The boy stood frozen in blank terror, school bag still hanging from his shoulder. That was the first warning. The headache was already blooming, extra edges pressing in around the ordinary world. For half a second everything held; then the second half of the warning arrived.

Recognition, not gallantry, moved him. He closed the distance in six steps, said a low “Hey,” and kept a single clear thought fixed: keep moving, keep the kid quiet, finish the handoff. The recruiter’s hand stayed inside the coat like a private appointment with gravity. Touma felt the clean, quiet cruelty of the moment sharpen into something like a paperknife held to the edge of thought, a pin driven through the inside of the world.

Then the unthink hit. Whatever connection or memory had been there slipped; the boy’s identity and any prior link to him were simply gone. Touma released the situation, stumbled, and for an instant felt relief. The second half of the feeling arrived immediately after—violation, then loss. A memory hiccup left only the aftertaste of familiarity that no longer had a name.

The whole sequence ran: notice → first warning → second warning → the move → the brief tableau of the wrist-grab and the hidden hand → the boy’s blank terror → recognition → the six steps → the quiet “Hey” → the target thought → the unthink → release → the stumble → half-relief → the second half → the memory hiccup → the loss of familiarity.
