Night of the 24th, in the Heaven month. On Christmas Eve, I had come to a place in the Demon Realm.

  Currently in front of me is a very cute Kuro in a red and white fluffy coat and a santa hat, instead of her usual black clothes.

  Her red trousers are also high points, and I personally like her outfit a lot.

  It’s just my personal opinion, but if she’s going to cosplay as Santa Claus, I prefer that she wear trousers rather than skirts.

  The top is a slightly larger coat and the bottom is a pair of red half-pants…… The trousers are hidden by her coat, and the beautiful legs peeking out are a perfect example of her vivacity, which makes me feel happy just by looking at her.

  Well, putting her cuteness aside, why am I being called to this place?

  [……Well then, Kaito-kun. This is where the Christmas Secret Mission starts!]

  [……Unnn?]

  Whoa there, it’s been quite a while she did this, but Kuro started saying incomprehensible again…… Christmas Secret Mission? It’s long and hard to say, but I can understand that she wants to do something.

  [Fufufu, you see, today’s mission is……]

  [Ahh, before that, Kuro…… Your outfit really fits you, you look really cute.]

  [Eh? Really? Ehehe, thanks.]

  I’m almost certain that Kuro would just swing me around again, so I immediately gave up on that. Since I didn’t know what was going to happen, I thought I’d give her a proper compliment while she still hadn’t said what she wanted, so I told her what I thought.

  Kuro chuckles happily at my words, before clearing her throat to regain her composure.

  [……Erhem. Well then, this mission is…… just something simple. You have to go into my home with me, move to the dining room without anyone noticing…… Secure the target and come back without anyone noticing!]

  [……Why bother with all that trouble……]

  [Fufufu, I know about it, you know? There’s that game based on an epic Christmas battle, where you go sneaking in homes, right!? Let’s do that!!!]

  [………………..]

  I have been expecting this, but it seems that she really got some weird knowledge from somewhere weird again.

  Epic Christmas battle…… Is that some kind of movie? As for sneaking in homes, she isn’t talking about Santa Claus’ story, right?

  Well, something like this is just like usual, and we’ll be able to clear up any misunderstandings later, so for now, I’ll just go along with Kuro’s game.

  Well, it may seem strange to sneak into your own house, but it doesn’t seem to matter to Kuro, as she seems to be quite lively while creeping along the walls of the wide hallway. It’s great if she’s enjoying herself.

  [……However, they’ll find out about what we’re doing soon enough, won’t they?]

  [It’s alright. I’m using Recognition Inhibition Magic, Presence Concealment, and a Soundproofing Magic so they won’t be able to tell…… Well, that’s unless you get too close to them though.]

  [……But in this path…… If someone comes in front of us, there’s no place for us to hide……]

  [……Ahh.]

  It seemed that she was quite preoccupied with that idea, that she didn’t think that this is a game where you get a game over when you were caught once.

  Well, we’re just playing around in the first place, so there’s no need to think about it too much……


  [I- It’s alright. It’s true that this is the area where everyone’s rooms are located but…… Everyone’s getting ready for the Christmas party today…..]

  [………………]

  I’m sure of it now. This is what they called “raising a flag”, right…… That means that there will definitely be someone who will come.

  As if to affirm my predictions, I hear faint footsteps and someone’s voice in the quiet hallway.

  [Awawawa, w- w- what should we do!? Someone’s coming!?]

  [……I don’t know if I should say that it is to be expected or not but…… wait, Kuro? What the heck are you—-?]

  [I- It’s an emergency…… Sorry!]

  As she announced this, Kuro reached out to a nearby door…… leading up to someone’s room.

  Thereupon, along with the sound of a lock opening, Kuro held my hand and pulled me into that room.

  [……Hey, Kuro?]

  [……What is it? Kaito-kun?]

  [Wouldn’t this end up like those tropes…… That pattern where people would come into this room?]

  [……N- No wayyy~~]

  My uneasy premonition became true once again, as the footsteps stopped in front of the room we were in, and I could hear the sound of a key entering the keyhole.

  [!? Kaito-kun!]

  [Eh? Uwaahhh!?]

  When Kuro heard the sound, she moved instantly, and with swift movements, she took me in her arms and jumped into a nearby closet…… Why the heck is she making things worse…… Isn’t this the pattern where it’s impossible for us to get out?

  While I was thinking about this, I looked through a gap in the closet with Kuro to see what was going on in the room, and the door opened…… and Acht and Eva walked in. It seems that this is their room.

  I’m pretty sure I screamed pretty loudly before we went into the closet, but the Soundproofing Magic is firmly in effect, and the two of them don’t seem to have noticed us.

  [……However, where in the world did Kuromu-sama go?]

  [Wouldn’t she be where Kaito is? I can’t think of any other reason for Kuromu-sama to “run away” from the party.]

  Whoa there, did I just hear something strange right there? I mean, it feels like I heard that the head of the castle seems to have run away from her own Christmas party……


  [……Oiiiii. Kuro?]

  [……Ehehe.]

  [No, no, you can’t just cutely smile right here…… What the heck are you doing!?]

  [I mean, I’ve decided to spend Christmas with Kaito-kun…… And yet, they said they would start a big party…… And before I knew it, they already started preparations……]

  ……I was wondering why she was trying to sneak in without everyone noticing, but it seems that this Underworld King came to escape from the party in the first place.

  But then, if that’s the case, why is she coming back to the place she escaped from before?

  [Hey, Kuro? I don’t think I heard the details, but what exactly are we going to sneakily get?]

  [……My newest baby castella, I forgot to bring it with me……]

  [……No, don’t you think that going that far wouldn’t be worth it?]

  [Eeehhhh, even though I went and made a “fried chicken”-flavored for today?]

  [Unnn, let’s stop trying to get it.]

  [……Eh?]

  No matter how I see it, that would be a punishment-type baby castella…… Moreover, since it’s Kuro we’re talking about here, she was probably quite fussy over it, so it would be a baby castella with real fried chicken meat in it or something like that, right? Unnn, I’ll never eat it.

  For the time being though, my objective from now on would be to escape this room after Acht and Eva are gone……


  [Hmmm, geez, what’s with you, Acht. You just suddenly……]

  [No, you see, we’ve been busy lately, and it’s been a while……]

  [ [!?!? ] ]

  Oi, you two, why the heck are you two so committed with the tropes? Geez, don’t you know that sticking on the template too much is bad too……


  Hearing their voices dyed in passion, I reflexively looked out of the closet…… and saw Acht and Eva hugging and kissing each other in perfect harmony.

  [Awawa, w- w- what should we do!?]

  [……Isn’t this bad? In that atmosphere, this obviously leads to……]

  [K- Kaito-kun, don’t look!]

  [Eh!? Wait, Kuro!? If you move in such a narrow space, uwaaahhh!?]

  Acht and Eva, who I feel like they’re getting in the mood by kissing each other…… Just when I thought it would be bad if I continued looking, Kuro flusteredly tried covering my eyes.

  However, we’re in a narrow closet, and we’re in a pretty tight position even before…… but that’s when Kuro moved, and as if we’re slipping into the gap between us, our bodies were brought close to each other…… and I felt something soft on my hand.

  [Hyaahhhh!? K- K- Kaito-kun!?]

  [Ahhh, errr, this is……]

  ……Currently in front of me is a lovely girl in a Santa costume, and my hands are touching her breast.

  It’s too dimly lit to see clearly, but Kuro’s cheeks seem to be blushing red and she’s impossibly cute.

  ……This is that, right? Was this one of those times when it’s the women who are making the advances? N- No, you see, it’s not like we can get out until Acht and Eva leaves anyway……


  [Ahnnn…… K- K- K- Kaito-kun…… Hnnn…… Fuaahhh……]

  [……Kuro.]

  [Y- You can’t…… Auu…… uuu…… N- Not in this place……]

  [I’m sorry, I don’t think I can resist anymore……]

  [Eeeehhhh!? Ahhh……]

  Each time my hand that was on her chest slightly moves, Kuro lets out a sexy moan, and along with our current situation, I felt passion that seemed to numb my mind.

  This might really be bad…… I don’t think I can stop. I need to somehow hold it down……


  [……P- Please be gentle…… Okay?]

  [!? ]

  Why the heck did you oust me right through my weak spot!? It’s impossible already…… I can’t stop anymore……


  [Acht-kuuuunn~~! Eva-saaaannn~~! Where are you~~!!! We need some help here~~!!!]

  [ [ [ [!?!? ] ] ] ]

  Right at that moment, Raz-san’s voice resounded, and Kuro and I, and of course, Acht and Eva’s bodies twitched.

  It seems that she came to call Acht and Eva for some help in preparing for the party.

  Acht and Eva hurriedly adjusted their appearance and left the room to talk with Raz-san, and at the same time, Kuro and I quickly escaped the room and ran out of the castle.

  [Ahh, it turned into something big……]

  [I think that everything that happened was Kuro’s fault though……]

  [Hmmm, I guess I can’t deny that.]

  Somehow managing to get out of the castle, Kuro and I chuckled as we exchanged words with each other while we walked through the city filled with the Christmas mood.

  I don’t really feel like going back to the castle again to pick up that baby castella, and Kuro seems to want to stay with me rather than join the party, so we decided to proceed walking around the city.

  [……Well then, how about we go on a date?]

  [Unnn!]

  After saying that, Kuro happily takes the hand I offered her and walks beside me, snuggling on my body.

  Well, I don’t know if I should say that it would also be quite busy when I’m with Kuro or not, but it’s always fresh and isn’t boring at all. However, even busy situations like this makes me feel very happy and I’m having fun being with her.

  [……Ahh, that’s right! Kaito-kun.]

  [Unnn?]

  As I’m feeling the happiness of being with Kuro, she suddenly raised her voice as if she thought about something, and tipping her toes, she whispered in my ear with a blush on her face.

  [……Ummm…… Let’s continue what we’re doing earlier…… after our date…… Okay?]

  [……Ahh, unnn.]

  [T- Then, let’s go!!!]

  [Eh? Wait, Kuro, don’t pull me too much……]

  As if to hide her embarrassment, my beloved lover walks with a smile as bright as the sun while pulling my hand away.

  Feeling the happiness of being able to spend Christmas together with her, but at the same time, feeling some anticipation for what’s about to come, I continued walking slowly through the Christmas streets with Kuro.

  [……By the way, Kuro. That situation we are in earlier…… Couldn’t we easily get out of that if we just used Teleportation Magic?]

  [……Ah.]
