Kazuma doesn't have a reason to be in the room after all he already has a pair of ghosts to deal with and he doesn't want to deal with any more ghosts if he can avoid it.
So he does what Ryūken asked him to do and teleports everyone back to Ryūken's apartment, the moment that both Ryūken and his son are sure that they are back in the Human world they leave.
Kazuma finds himself standing in the living room alone, listening to the door close behind them.
"Hey, you haven't eaten anything, why don't we go shopping and I'll teach you how to cook some of my " Masaki says t him as she walks in front of him.
Kazuma smirks when he sees the woman's smiling expression, he knows that she's trying to cheer him up in her own way, and it's because she said something to him, that he knows that he isn't completely alone here.
Even if normal people can't see Kanae and Masaki he can and that's enough, after all, normal people and people that can't defend themselves shouldn't be involved with things that Adventurers deal with.
"Yeah, might as well use this thing as long as it has money in it." Kazuma says to Masaki as he starts to walk towards the door and then out of the apartment.
The first thing that he notices when he closes the door is how cool the wind feels, he knows that he fell asleep and so some time must have passed while he was asleep, but he doesn't know how much time passed while he was in Hueco Mundo.
After all, he doesn't know when Ryūken arrived in the apartment and how long the man was in there before he woke up, so he has no idea if time passes differently in Hueco Mundo.
"Kazuma, you know that someone such as yourself can use his powers to do certain things if you want." Kanae says t him as they walk down the empty street that is slowly getting darker.
Kazuma doesn't bother to turn and look at her because he knows that she's right, any and every adventure knows but few of them ever use their skills for anything that isn't fighting monsters or just playing harmless pranks on their friends.
"If there's a girl that has caught your eye neither Masaki nor I will object or try to stop you, if you decide to force." Kanae says to him but she stops talking when Kazuma stops walking.
He looks at the sky which is even now becoming darker before he starts to answer Kanae.
'Pass, I already was surrounded by a bunch of crazy women and besides I have the two of you now, so no I'm good." he says to Kanae and Masaki before he starts to walk again.
As Kazuma walks down the empty streets he listens to the sound of his footsteps, the sun managed to completely go down by the time he manages to reach the grocery store.
He can't help but smile as he looks at the different kinds of junk food that he would have bought in the past, and would have bought now if he hadn't felt both women's eyes every time he tried to grab one.
"So besides Hollows and Soul reapers what else is there?" Kazuma asks the two women, as he grabs several packs of raw meat.
"Well, there are a lot of things like normal animals because they have souls too." Masaki says to him as she points towards a pack of chicken that's on special.
"There are also creatures that live n the other realms that you should avoid, like the Feral Beats and the Dragons." Kanae says to him as she looks through the fruits and vegetables for the ones that haven't spoiled yet.
"Kazuma." both Masaki and Kanae say to him as they both point at different things that they like, while at the same time, they somehow manage to telepathically tell Kazuma that someone is watching him.
Kazuma doesn't react, not because he doesn't believe that the person watching him can't hurt him, but because the person isn't a threat at the moment.
Maybe he or she is wondering who he is or if something is wrong with him because, from a normal person's point of view, he's been talking to himself this entire time.
Or they are just gathering information for now and so they aren't an immediate threat, but the chances that someone knows anything about him so soon are small because who would know about him?
Luckily for him, the grocery store is open late so he doesn't have to rush to pay before the employees have to close, unfortunately as the cashier starts to scan the last of the food his energy detection skill begins to activate.
He ignores it, but he still uses the reflective plastic that's behind the counter to look for any signs of who might be watching him.
"Damm.' he says to himself when his eyes meet the yellow eyes of a black cat.
"Is there a problem? Do you want to put something back?" the cashier asks him.
'No, I just forgot something." Kazuma says to the man behind the counter before quickly turning around and grabbing the nearest bag of potato chips and then turning back before handing it to the cashier.
"Kanae, Masaki is that cat a ca or is it something else?" Kazuma asks both women who vanish before turning to look at the black cat.
"I can sense some spirit energy but it's not a threat." Masaki says to him as she reappears next t him, just as he hands the cashier Ryūken's card.
"It's ignoring you now, but it was who we sensed earlier." Kanae says to him as he leaves the store with both hands filled with grocery bags, but unlike Masaki, she decides to stay invisible.
As he walks back t the apart, meant he notices that the streets are unusually quiet, because unlike before he can hear his footsteps making some sort of echo every time he takes a step.
His evasion and enemy detection skills flare and force him to jump onto a nearby wall, just as a large snake that has the white mask that the Hollows are supposed to wear buries its head where he was walking a moment ago.
'I'm glad that I didn't buy anything that breaks." Kazuma says to himself as he waits for the giant snake to attack him again, but the attack never came as the same woman that he saw a few days earlier jumped down from the sky and sliced the snake's head in half.
"Kazuma get out of here before she sees you." Kanae says to him and Kazuma teleports back to the apartment when he hears the fear in her voice.
