Like all Jihibiki, Junichiro has an extremely refined sense of hearing. So refined, in fact, that he's able to hear anything and everything going on inside of the room whose door his ear is pressed up against. Or, rather, he's able to hear the *Lack* Of anything and everything. Not a single heartbeat echoes within the room, not even after listening for well over fifteen seconds. 

In that time, of course, he's able to construct an extremely refined map of the room based on the reverberating sound from the bazaar itself against the floor and the specks of dust upon it. It's a relatively open space with a few scattered tables and chairs within. A few sheets of paper are scattered on the floor here and there. There's an empty cork-board on the far wall. And, of course, another door further within, leading to the back of the closed-down shop where the supposed secret entrance actually is. According to the report, at least.

A few roaming bazaar-browsers give the trio of Military Police shinobi confused glances, but they aren't questioned at all.

"... There is nothing..." He spoke quietly, a whisper as he would stand. "And that... Is concerning. I could not even sense so much as a fly, and while I do not currently detect any traps... This is only the front... As such." He would open the door, with force if needed, breaking the knob if necessary to push the door open, and speak softly. "Once we are in, I would hope the area to be secured, there is a chance that the enemies may hold the area hostage with some kind of mechanism or technique should they find themselves cornered." 

His shield was ahead of him, as he continued ahead. "Our colleague mentioned the secret entrance to be near the back of the establishment... I would be wary, however, the chances that they are aware of our meddling are slim, but not nonexistent." He kept his eyes and trained workers mind peeled for any contraptions, and as he did last time with the other door, would inspect the 'secret entrance' with much scrutiny.

Shinpi didn't know anything about what Sensory was like, but to hear that Junichiro couldn't sense *Anything* Was a bit concerning to him as well. The only thing that he could really hope on is that the previous owners were very vigilant about their pest removal, because he didn't even know what the alternative *Could* Have meant. Regardless, Shinpi simply nodded towards Junichiro and kept in formation behind him.

While they worked, Shinpi made sure to keep his eyes and ears open for even the smallest little detail. Anything that didn't sound like it fit in with the ambient sounds of the surrounding area, whatever that may be. For now, that was really all that he could do.
