In the end I told her about the incident in the stairwell. If there was an intruder, she needed to know about it, simple as that. “Miss Izayoi,” I said hesitantly, “there’s something you should know.”
She stopped me by holding up her hand and saying, “Sakuya, just call me Sakuya unless we have guests.” After I nodded she asked, “So, what do you need to tell me?”
I took a deep breath and replied “After waking up Fla-, the young mistress, I stepped out as she bathed and got dressed. While I waited in the stairwell, all the candles went out at the same time. I could hear footsteps for a few moments, but they stopped after a couple minutes. I was worried that it was a trap to lure me from the door, so I stayed where I was.” Sakuya stared at me with an expression that was hard to read. It was like she believed me, but at the same time didn’t. “The candles sprang back to life after the footsteps stopped which was just before Willow and the young mistress came out of the room. They didn’t mention anything strange, so I didn’t mention it to them and on the way back up, I didn’t see or hear anything out of the ordinary.”
She stood there looking thoughtful for almost a minute. She looked back at me seriously; her eyes flashed red for a moment. “Those candles are magically enchanted to never go out or melt. Patchouli would have let us know if she was going to do anything with them.” She dug out her pocket watch and said to me, “Deliver the food to the young mistress and meet me at the gate.” I couldn’t even respond before she vanished. The tray of food she was holding wound up in my arms somehow.
I quickly brought the tray out and set it in front of Flandre. After I removed the top, she started tearing into the array of breakfast foods that was before her. I didn’t really pay too much attention to it because I had to meet Sakuya. “If you’ll excuse me, I need to help Sakuya with something.” Flandre nodded with a piece of sausage hanging out of her mouth and Willow waved shyly as I left the dining room.
I rushed to the gate, nearly bumping into some fairies on the way there. Oh, don’t get me wrong, I wasn’t running. I just wasn’t really paying attention to my surroundings. Anyway, when I arrived at the front gate I saw Sakuya talking to Meiling. “-dn’t sense anything?”
“Nothing,” Meiling responded looking mildly insulted. “No one has entered, or left, the mansion grounds since Reisen got here.”
“Did she arrive alone?” I asked, startling the two of them in the process. “Maybe someone snuck in then?”
The two of them looked at me with surprise, then at each other. “I didn’t think about that,” Meiling said slowly as she started to rub her chin thoughtfully. “If two people enter the grounds at the same time, I wouldn’t even notice.”
“That,” Sakuya sounded annoyed, hesitant, and confused all at the same time, “sounds like a problem.”
“It normally isn’t an issue, but if someone entered the grounds without me noticing, it would have had to been that way.” She sounded confident, but her body language said that she was still having trouble accepting that as truth. “I’ve never had anyone try to sneak in that way though,” she admitted. “It would be extremely difficult and require precise timing.” Meiling then looked at Sakuya. “I wouldn’t normally admit this, but my ability to sense people entering the grounds is a passive ability most of the time. I can’t really use it to find their exact location.” She took a deep breath and pressed her hands together in front of her chest.
She stayed like that for almost five minutes, and every time I went to talk Sakuya silenced me by putting a hand against my mouth. For the record, she has very soft hands. I didn’t expect that from someone who does so much work.
“I can’t tell where, but there is a presence that shouldn’t be here,” Meiling finally said.
Sakuya’s face darkened as she spun on her heels. “Both of you, head to the mistresses room. Now!” Ordered the maid before she flicked out her pocket watch and disappeared. Meiling and I nodded at each other then walked inside, up the stairs, and towards Remilia’s room where Sakuya was waiting for us. “I already told her that there’s an intruder, you two just need to tell her what you know. I’m going to keep an eye on the young mistress and make sure she stays safe.” She vanishes once more and Meiling knocks on Remilia’s door.
“Enter,” Remilia sounded impatient, and given the situation had every right to be. Meiling opened the door and walked right in, but I followed hesitantly. I wasn’t sure why, but I felt as though my life was in danger. I stepped into the room and heard the giggle of a young child. It was faint, almost nonexistent, but it was there all the same. I turned to look out into the hallway, but I saw nothing. “Is something the matter?” The mistress asked me with great annoyance.
“I thought I heard something just now,” I responded honestly. “It sounded like a child’s laughter.”
“It was probably Flandre or some of the fairies,” she said gesturing for me to close the door. Once I did she turned to Meiling, “Sakuya said there’s an intruder. Who is it, how did they get in here, and why aren’t they being escorted out yet?” She didn’t hide her irritation in the least.
But, that didn’t faze Meiling at all. “We don’t know who it is, but we think we know how he or she got through.” Remilia, who was sitting on the edge of her bed merely watched Meiling as she spoke. “The intruder likely entered when Reisen arrived yesterday. As you may know, when two people enter the grounds at the exact same time, I don’t register that it’s two people. But, when I did an active mental search of the mansion, I found a presence that shouldn’t be here. Sadly, I can’t tell where they are.”
Remilia nodded and turned her attention to me. “And you encountered the intruder?”
“In a sense,” I said, feeling a little nervous at the sudden attention. “I was in the stairwell while your sister was bathing. The candles lining the wall went out at the same time and I could hear footsteps above me, but I never heard a door open or close. The footsteps were faint, but likely deliberate. But the footsteps stopped and the candles came back to life shortly before the door the young mistress opened her door.”
“Why didn’t you confront the intruder?” She glared at me like I did something wrong, which I found insulting.
“Given the lack of sight, and the multiple unknowns in the situation, I opted to guard the door to prevent the intruder from reaching your sister. If that was the intention that is.” I met her gaze and responded honestly.
“Flan can handle herself,” Remilia said flatly.
I got increasingly annoyed with her tone. I did what I thought was best in that situation, she should have been happy I was protecting her sister! “As true as that may be, you tasked me with taking care of her. I chose the action that would be more likely to keep her out of harm’s way. Plus,” I added, “She was in the middle of a bath. She wouldn’t be expecting anyone to just barge in and attack her. I didn’t want to risk it.”
Remilia glared at me for a moment longer before relaxing and saying, “Very well then. I apologize for questioning your motives, but I have had a few attempts on my life recently and I would rather not wake up to a silver knife against my throat.” Meiling stared at the vampire in surprise. “Oh, do not worry Meiling. It was not here, it was on my way back from my trips to the Hakurei Shrine.” Meiling relaxed, but only slightly. I guess knowing it wasn’t her fault for not noticing a hostile presence helped. “Anyway,” Remilia said as she stood up. “Meiling, go lock the doors. No one enters or leaves the building, which includes you. Any fairies outside are to return immediately, those that do not are to be locked out until the intruder is caught. Once the doors are locked I want you to tell Patchy and Koakuma. I want them to have familiars scouring the entire mansion.”
Meiling bowed and said, “Yes ma’am!” Hurrying out the door she nodded politely to me.
“Ryuga,” Remilia said quietly. “I am going to have Sakuya keep an eye on Flandre. Whoever this is seems to be good at hiding as Sakuya is unable to locate whoever it is when she stops time. If we cannot find the rat by eyesight, we’ll have to rely on our other senses. If you could hear their footsteps, then you might be able to hear their breathing when you are close.”
I probably shouldn’t have, but I interrupted her by saying, “I think you’re giving me too much credit. My hearing is good, but not that good.”
“I know,” she sighed, “but your senses are, in fact, heightened due to the vampire blood flowing through you now. You just need to learn to pay attention to them. If you focus, you should be able to hear, see, smell, feel, or even taste better than previously. It requires a good amount of focus in the beginning, but one day you will be able to do it without much effort.”
I stood there silently and focused on my sense of hearing. I could already hear her breathing, but as I focused it became clearer. I could hear fairies chattering in the halls, even a toilet flush down the hall. I couldn’t help but laugh at my success. I quickly forced myself to stop though. “So, what exactly should I do?” I asked my mistress.
“I want you to start patrolling the mansion at night, when everyone else is sleeping since it will be too noisy during the day. For now, eat, rest, get some training from the others, or you can begin your search now. It is up to you.” She gave me a look of confidence and support.
“W-what should I do if I encounter the intruder?” I asked hesitantly.
“Ideally, I want you to alert Sakuya and Meiling, but that would only serve to give the little rat time to find a new hiding place,” she shrugged as she spoke, which seemed unlike what you what you would expect from her. “If you think you can, take them alive. But if they prove too difficult to subdue, don’t hesitate to go for the kill.”
I nodded solemnly. If I had no other choice, I would kill the intruder. It was simple, or so I thought. But that time was still a little ways off. In the meantime, I needed to prepare, so I…
 Training with Meiling (Hand to hand combat)
 Training with Patchouli (Practical/Offensive magic)
 Training with Koakuma (Illusion/Charm magic)
 Training with Sakuya (Weapon Based combat)
 Training with Remilia (Vampire Powers)
-() With someone (Choose who)
-() Alone (Choose where)
 Start your search now
It's up to you how you go about your training. You could completely neglect it, but that leads to a variety of issues. You can max out your skills with TWO of the trainable abilities, and get halfway through another. Or you could try to balance it and see how they mix. And yes, there is a merit to both "Hand to Hand" and "Weapon Based Combat". Resting with a character is obviously different than training with them.
If you want I can tell you what what Ryuga's relationship levels with the residents of the mansion are. An example is,
That may or may not be her actual rating right now. But, it would go from -10 to +10. At minus ten, they would be actively trying to kill you, so I can assume you know what plus ten is. Just let me know if this appeals to you.
