When Diego came to this world, he was met with a harsh beginning. Not a day later and he felt like he was being treated as a house guest. Then again, he didn't really do anything necessarily evil that would warrant punishment.

Diego had been led off by the Kakushi and was brought to a very beautiful building. It was annoying how many bugs flew around the place though. Once they were positioned in front of the residence, he could hear yelling from inside, which didn't do much to calm his nerves about this place. Up close to the building, he noticed a pretty female demon slayer with dark hair and purple eyes. She just stood there as the Kakushi explained the situation, staring directly at them and yet… not at the same time. A second female came out, sweating like she had been running around all day, and greeted them. Now, while Diego was an adult, he wasn't used to being so tall compared to fellow humans. Maybe this is what most Americans met when they said Asians were short? Whatever the case may be, he practically towered over this girl. She stood about to his chest at best, but that was with her straightening up. Was she blushing? Maybe, he did often have an appeal over women after all. Thank god he didn't go off for the younger types though. She introduced herself as Kanzaki Aoi, and the silent girl as Kanao Tsuyuri. Diego, in return, introduced himself. He bowed slightly, and was proceeded to be let in by them.

Crossing room to room, he was brought to a curious three. One of which was the other blonde he met from the tree, another was a redhead, and the last was a boar mask. Oh wait, the last one was a person. The first two he mentioned looked at him while the pig didn't seem to be moving at all. Was he dead?

The blonde began to cry out at Diego. "You're the guy who sat next to me on that tree! Please help me out of here, they're torturing u-"

The yellow haired yakuza was whipped across the head by Kanzaki, who seemed to have enough of him. Diego gave a tiny look of sympathy at him and looked at the red haired boy. He waved and introduced himself as Tanjiro Kamado and the yellow one as Zenitsu Agatsuma, but they go by Tanjiro and Zenitsu. He also mentioned the pig was a guy named Inosuke, but Diego didn't quite catch the rest. Regardless, Tanjiro was kind of charming to Diego, even if this was just an introduction. Diego waved back and also introduced himself along with why he was staying here. He could already assume that these people were here for treatment, but they only confirmed his suspicions by relaying it back at him after his introduction. The rest was kind of awkward, as Zenitsu wouldn't stop shouting at the children of the establishment about the medication. Diego just kind of sat there before a very angry Kanzaki led him out into the room next door. She mentioned that his training would be tested tomorrow at the doorway, but he was more focused on the room itself. It was quite small, but the bed and table across from his position were quite nice. He hadn't cleaned his gun in a long time, so maybe he could tonight on the table. Over all, a very simple and small room. He couldn't be more pleased about it though.

As Kanzaki continued to inform him of eating hours and some check ups on his health, he entered the room and felt around. The walls were thin and the doors were meant to slide rather than push/pull open. He didn't mind this, but he wished there was just a tiny bit more privacy. Either that or he just didn't want to hear Zenitsu scream all night long. Taking in some fresh air by opening a nearby window, he heard a voice break in through the air.

"Hello."

Diego hadn't even noticed Shinobu entering the room. Kanzaki, who had asked Diego to simply call her Miss Aoi, was also taken back by her sudden appearance. Still, she left the room for Shinobu to talk to him as well.

"I assume you have already been informed about your stay, but I would like to formally introduce myself. My name is Shinobu Kocho, the Insect Pillar. Before we get started with training tomorrow, may I be informed of the 'power' that you possess? It would make things much easier, you see."

Diego pondered on what to tell her and what not to tell her. At least she could know about the basic facts of his stand, but not the time stop or it being a seperate being from his own self.

"I am able to detect and move at a very high point of speed. I'm not sure about how fast, but it's enough to catch bullets flying at me from very short distances."

Shinobu seemed to be intrigued by this information.

"I am also able to pick up and destroy very dense objects as well. I would say it's easy for me to destroy entire buildings like this one within minutes, but you can see for yourself tomorrow."

Shinobu just sat there with a smile. Unbeknownst to Diego, she wasn't believing anything of what he just said. She was only going along with it so that there wouldn't be any arguments from him. After his introduction of power, Shinobu stood up and addressed him.

"Well, as one of the highest ranking demon slayers, I am actually very physically weak. Power isn't everything, and I seem to be on the more… intellectual side of things. Therefore I have researched poisons to destroy demons from the inside out. You may have seen one of my victims, based on the Kakushi's remarks of where they found you. So I must remind you that power isn't everything. It's intellect, abilities, and breathing."

Diego sat back for a second. Maybe he was too upfront with his abilities? He didn't know, and Shinobu was very hard to read as well. Wait, breathing?

"You mentioned something about breathing?"

Shinobu began to chuckle a little before continuing. "Yes, breathing is a slayer's form of increasing their reflexes and strength, but it can also produce amazing abilities. An associate of mine is able to have abilities related to water attacks, another is able to do flame, and so on."

Diego took that as a universal stand system, but he would have to see it in action to fully understand it. So he just had to breathe certain patterns in order to increase his reflexes? That could pair up great with his sta-

"Of course, you would only use these abilities with a Nichirin Blade, a special blade all demon slayers use that is able to harness the sun's rays. That is, after all, how you are able to kill demons. Other than crushing their heads, it's the most effective as well. We could try producing special bullets to try and blow out a demon's brains however! Going on with that, I would presume that you have been unconsciously doing breathing forms if what you say is true. Sometimes it just comes naturally to people!"

Diego deflated after hearing that news. He wasn't of any interest in learning the blade, and his stand could provide more than enough if he just needed to crush the head of a demon. Shinobu said she had something to do and left him to be after that, and Diego was left to his own devices.

First order of business was to clean his clothes and revolver. Most of the outfits there didn't fit him, so he had to stretch them out a bit. All this did to serve him was leaving his abdomen and lower arms exposed, along with his lower legs as well. He brought the dirty clothes down to (what seemed to be) a laundry mat and let one of the young girls take it. Were the only workers here girls? That was going to be awkward with someone like him around.

Back in his room in the later hours of evening, Diego was checking out his piece. It was a simple 1890 Colt revolver with some engravings on the hilt, and it served him well for the times he used it. Thinking about it now, how were they going to design bullets here? They had never made guns before from his knowledge, and none of them here seemed to be smiths. Maybe they got them from someone else? He pondered this for a little while before finishing the revolver's cleaning. Looking over a little bit, he could spot the cold remains of dinner that sat on the edge of his desk. For what was basically a medical institution, the food was actually pretty good. Maybe one of the young girls helped cook the food.

After the cleaning process was done, he reassembled his gun into its original form. Stashing it away next to the bed, he thought that he might as well do some sightseeing before the night had truly ended. From the temple designs, he knew he was Far East He just had to deduce which country from the East at a later point in his stay here. Definitely not his world though, or he would've encountered a stand user by now.

Diego had a pause in thought thinking about stand users all of the sudden. Perhaps they do exist in this world as well, and he just hasn't encountered one yet. As his thoughts trailed off, he was oblivious to a watchful Shinobu on the rooftop. She looked over his body with curiosity in her eyes. She questioned herself a lot about who Diego was, so she may as well see what type of person he is when no one's around. To her surprise however, Diego was just sight-seeing the place, taking in the atmosphere before heading off into the sleeping quarters. Disappointed would be a good word to describe how Shinobu felt about what just happened, but she wasn't about to be the type who expresses it physically. She went back to her own duties as Diego went back through the estate and into his room. Sitting down on the bed, he tucked in for a night's rest and mentally prepared for tomorrow's show.
