climbed up an alley relatively fast

Suddenly, he heard the (sadly not high-pitched) voices of numerous girls from the main
road. It seemed a wild animal search party had already been formed out of volunteers.
Kamijou immediately looked further down the narrow alley.
(No, I have no idea where this leads. They might be advancing from both directions or it
might lead straight to another major road. I need a safer way out of this.)
Kamijou glanced around the straight and narrow alley, twisted his head around, and
then froze in place.
What he saw was…
***
Multiple sets of footsteps entered the narrow alley.
“What!? He is not here!”
“Was that witness testimony inaccurate?”
“…U-um, senpai. That was not some new type of UMA not recorded in any animal
encyclopedia or a materialization of all the girls here’s desires for some as-yet-unseen
gentleman, was it?”
“He was nowhere near pretty enough to be that.”
“Oh, of course!! No one would want a reaction performer like that!!”
(You don’t have to insult me like that!) cursed Kamijou in his heart.
He was up above them.
He had pressed his arms and legs against the buildings on either side of the narrow alley
to climb up to the fifth floor. To make sure they would not look up and spot him, he had
climbed onto the roof and rolled onto his back.
