I know girls don''t wear brassiere during their sleep, but that''s not important.

    I''ve seen Restia and Ruby n?k?d so many times that I developed a tendency to take their n?k?d body the same as common background.

    Yet— I''m getting nosebleed.

    Words could not describe the intensity of my current feeling.

    …Truly beautiful.

    Is probably the only two words that are in my mind now.

    "NGAHH— MY HEAD!? IT HURTS!!!"

    With Restia''s sudden scream, I was pulled back to reality.

    Which then, I quickly cover Kuroyuki''s ?h?st with her ripped nightgown.

    While telling Restia that, I raised my head and pinched my nose to stop the nosebleed, with the phone still sandwiched between my head and shoulder.

    "Big brother… it''s definitely you," Restia uttered. "And what happened to your nose…? Your voice seems clogged."

    "…I had nosebleed," I replied.

    "You are the one who needs a doctor." Restia retorted.

    "No, Restia… this is perfectly normal."

    "Nosebleed does not have anything to do with s?xu?? arousal."

    As soon as Restia made that remark, my nosebleed stopped.

    "Give me a sec, Restia… let me carry Kuroyuki back to her room."

    Placing the phone on my bed, I carried Kuroyuki in my arms, taking her to her room.

    Aside from the smell of my own blood, then it''s Kuroyuki''s scent, perhaps.

    I looked around.

    Her room''s design looks exactly the same as my room, only with the furniture at the other way around— like a mirror.

    Aside from that, there''s nothing special.

    With every movement as quiet as possible, I carefully placed Kuroyuki on her bed.

    It was then, she made a roll— revealing her ?h?st once again.

    SPURT.

    … I''m getting nosebleed again.

    Luckily I managed to prevent it from dirtying Kuroyuki''s bed by blocking it with my clothes.

    Once again, I covered Kuroyuki''s ?h?st with her nightgown.

    I figured it''s possible to catch a cold with that exposed ?h?st sooner or later; I added another layer… which is— her blanket.

    Then, I took a video as proof that I returned her to bed.

    Thus, I returned to my room while closing the door— activating the soundproofing mode in my room.

    "A minute, Restia," I yelled.

    ……………………………

    After washing my nose and changing my clothes, I switched my call to loudspeaker mode, again lying on my bed.

    "What took you so long?" Restia complained. "Shouldn''t you just throw her to bed and leave immediately?"

    "Eh… but I was always gentle with you and Ruby."

    A third-person perspective speech— Restia had forgiven me.

    "Jealous?" I asked.

    "…Yes."

    "How honest. But that''s what I like about you, my cute little sis."

    "Oh, big brother…!"

    "Speaking of which, what do you think of Kuroyuki?"

    "Restia really hates to admit it…… but that snow woman is the type of person that anyone could fully rely on— she''s flawless."

    "My cute little sis is acknowledging another girl…? Now that''s rare." I said.

    "...I don''t want to talk about her," Restia uttered. "…Now tell me what happened during our call."

    "Is it see-through?"

    "Aren''t you supposed to ask what happened, Restia?"

    "She''s seducing you, is she? Why is she wearing a see-through nightgown!?"

    "It''s not really see-through-able."

    "The next time I''m sleeping with you— I will be n?k?d."

    "Geez, it''s not like you''ve never done this with Ruby before… I even lectured you for hours. Plus, you will catch a cold."

    "Big brother is only allowed to ogle at my body…! Oh, and Ruby''s."

    "Don''t bother. I already can''t feel anything down there for years, Restia."

    Speaking of which… I did feel something down there when it''s Kuroyuki…

    "RESTIA."

    "—ehem, so what happened? Her nightgown."

    "Accidents, Restia," I murmured. "It''s just that Kuroyuki''s nightgown could not withstand her weight."

    "This means she fell asleep when you are rubbing her cheeks, so you need to grab her on her nightgown to stop her head from bumping your knee… but she''s too heavy, that''s why her nightgown ripped?" Restia murmured.

    Feeling surprised by Restia''s guess, I inadvertently look around my room.

    "…Restia, did you perhaps— placed a camera at my room?" I murmured. "How come your guess is completely right on the spot?"

    "Because Restia loves big brother?"

    "It doesn''t sound convincing at all, Restia. I love you just as much you love me, so why can''t I make an accurate guess?"

    "No no that''s not it— big brother could do the same as well," Restia told me. "Take a guess; why is it that Ruby and the others aren''t talking to big brother right now?"

    Come to think of it, I really can''t hear their voices for a while now.

    Aside from Restia''s voice, I faintly heard the sound of the wind blowing.

    Knowing Restia and Ruby, it''s probably…

    "Hmm… Because they were too noisy and always interrupting our conversation, that''s why you flew to the sky with your magic spells?"

    "See…?" Restia murmured. "Right on the spot."

    "As I thought, it doesn''t seem convincing at all…"

    With that, I heaved a sigh.

    "Save the small talk for later, Restia. Let''s get to the details today." I murmured.

    "…SO? HOW MANY NEW GIRLS YOU MET TODAY?"

    "…My cute little sis, weren''t you being concerned on the wrong subject?"

    "You met two new girls today, don''t you?"

    "Hey— stop looking at the profiles of the S Ranked students. Besides, nothing happened— okay?"

    "But my five migraine headaches… and adding those three centre headaches…"

    "I have been to the entire First Year Faculty and East Cafeteria today." I continued, while deciding to ignore Restia''s remark.

    "That''s one block less than yesterday…!" She uttered. "Are you even doing your job given by ''you'' properly?!"

    "I am! I have been looking around just like what ''I'' told me…!" I said. "Oh, come to think of it… I''m going to the basement at the White Mansion tomorrow to take my gift."

    "Gift…?" Restia murmured. "Ah! That enrolment gift that guy owed big brother! What is it anyways…?"

    "He says it''s a legendary black sword."

    "Eh— is big brother sure that guy isn''t messing with big brother?"

    "He already messed with me, Restia… It was just this morning…" I sadly replied. "But Fortunately, Nightmare got to land some satisfying punches on him."

    "Big brother… you do know you are punching the person with the highest authority on the entire Central Imperial Island, right…?"

    "Yup," I replied. "That''s what Nightmare and I agreed on."

    "…Nevermind," Restia replied. "So… about the so-called legendary black sword… is it real…?"

    "Well… putting the legendary stuff aside… that sword is real, Restia. Kuroyuki Shiroha tried to take that sword before, but she failed."

    "So this is the only mission she failed…" Restia murmured. "There are so many restrictions… I would definitely refuse this."

    "Oh, you already read the files Kuroyuki gave me?"

    "…N."

    "I will text you when I''m going to enter the basement tomorrow. If I didn''t text you again after two hours, make sure you call that bastard to get me no matter what, Restia."

    "…Understood," Restia replied softly, seeming unwilling to let me go.

    However, she didn''t stop me because she knew it would be pointless to do so.

    "Don''t worry, Restia," I told her. "I''m terrified of dying… so regardless of the danger of it— I will definitely make it out alive."

    "Not just alive— you need to make it out in one piece." Restia reminded me.

    ?"Understood, my cute little sis," I replied. "By the way— how are you and Ruby doing?"

    "Ever since big brother isn''t around… everyone looks gloomy and depressed."

    "…Are you sure it is ''gloomy and depressed'' for Ruby?"

    "Well… Restia gave Ruby big brother''s boxers, so Ruby was satisfied with it for now." Restia replied. "Ruby''s been sniffing it in every five minutes."

    "What!? How did you get my boxers!? I thought I stuffed everything in my bag!"

    "Hmph. This is what you get for underestimating me."

    "Indeed, I underestimated your shamelessness. Now that you told me… I believe, that''s not the ONLY thing you took."

    "N-Ngh…!?" Restia panicked.

    "Spit it out, Restia— WHAT ELSE YOU TOOK?"

    "Big brother''s T-shirt and pants…" Restia murmured. "B-But, Restia only wear them after Restia got out from the bath…!"

    "That''s not the problem." I retorted. "Just wearing it is already wrong."

    "It feels like big brother is always hugging Restia."

    "There''s no way I could hug you for 24 hours, you pervert."

    "Restia doesn''t mind being a pervert if Restia could stay with big brother."

    I deliberately heaved a sigh afterwards.

    … There''s no way for me to stop this perverted little sister, huh.

    "Alright, Restia," I murmured. "It''s about time you let me talk to them as well."

    "…N."

    As soon as Restia responded, I could gradually hear Ruby and the others— it seems she''s descending to the ground.

    "NYAA…!"

    "KYAA!?"

    "Ruby got the phone…!"

    "Nice one, nya…!"

    Seems like Ruby and Felix have been ambushing Restia on the ground to get her phone.

    "Myaster…! Restia is very selfish nya…!"

    "M-MEOW…!?"

    As soon as Ruby talked to me, I heard Felix''s scream. It seems Restia caught her.

    "What do you idiots know about my painstaking for my big brother…!? Coarctant, serpentes terrae!” (Constrict, Serpents of The Earth!)

    As soon as Restia chanted, I could hear the hissing of a thousand snakes…

    "NYAAA!!?"

    …plus Ruby''s scream.

    “MYASTER…! HELP RUBY NYAA…!!!”

    "I know you could handle it— good luck."

    "Myaster, you meanie…!" Ruby protested.

    POP.

    "OWOOOOOOO…!"

    BOOM.

    Seems like Ruby transformed into a Fenrir Wolf and used the glacial beam to blast Restia''s Binding Earth Snakes.

    "Not bad, Ruby," I told her. "And Restia— calm down, will ya?"

    "……If you say so."
