Chapter 2550: Extra Chapter: April Fool's Day Operation ~ ~ A Failed Plan ~ ~

This chapter is updated by JustRead.pl

I opened my eyes to the morning sunlight and sat up in bed and somehow, there was an intruder standing by the window with arms crossed, wearing a fearless expression with the light streaming in behind her.

[Answer me, Kaito. What day is April 1st!?]

[Eh? April Fools Day.]

[Wrong! April 1st is World Serious Day! I just decided that a moment ago!!!]

[Then theres no way Id know that, right!?]

I really wish she wouldnt throw completely unknown information at me the moment I wake up. Somehow, it feels like its going to ruin my morning.

Well, putting that aside, the person in front of me is Serious-senpai, who shows up out of nowhere about once a year.

Shes not a bad person, but theyre full of mysteries, or rather my honest impression is that theyre just generally hard to understand.

[I see. Given the timeline within the story, its probably not actually April 1st yet, so I understand why youd be confused. Considering how much time has passed since the birthday chapter, maybe its around the end of the year here? Anyway, I completely understand your confusion.]

[No, Im pretty sure youre not understanding my feelings at all]

What Im feeling right now is more like What the heck is this person even talking about?. Sure, I might be confused and bewildered, but thats not because of the timeline, its because of what Serious-senpai is saying.

What is this feeling I just woke up, but I already want to say good night and go back to sleep.

[But think about it, since entering Afterstory, you could say the storys timeline has essentially entered that kind of mysterious time-space often seen in fiction. If thats the case, then things like seasons and months are trivial issues.]

[Fuaaahhh what do you mean by mysterious time-space?]

[You know, that thing you see a lot, where the characters dont advance in grade or age, but the seasons keep changing, and events like Christmas and New Year keep happening over and over.]

[Ah, yeah, you see that a lot. Doesnt it usually have some kind of name? Im sleepy Senpai, Im making coffee, do you want some?]

[This guy sounds completely uninterested ah, Ill gladly take the coffee.]

Honestly, after meeting her this many times, Ive gotten used to it. I think its just right to ignore about 70% of what Serious-senpai says. Their mood swings are extreme, and they suddenly say incomprehensible things, so even if you listen seriously, you just end up confused. Its best to just catch the main points and call it a day.

[So, Serious-senpai, you came again this year from that room with no exit where you can only go outside once a year a place that sounds almost like torture just hearing about it, right? What are you planning to do this time?]

[Heh, Im glad you asked. Thinking about it, Ive always been passively waiting for seriousness until now. But thats no good! From here on, Im going to pursue seriousness more proactively, and as the first step, Ive made preparations in advance this time.]

[Preparations? For what?]

[Behold!]

[What is that?]

What Serious-senpai pulled out was a palm-sized object shaped like a globe made of a crystal-like sphere. It was a rather mysterious item. It looked like a magic tool, yet somehow also had a mechanical feel to its design.

[To put it simply, its like a teleportation magic tool. I had that crazy god who often comes to my place make it.]

[Ahh, the one who keeps eating you when you turn into sweets?]

[Lately, shes even started controlling how I transform beforehand before eating me. Shes omniscient and omnipotent, if shes gonna go through that much trouble, she could have just created the finished product themselves. Why is she so adamant about eating me Thats something I have no clue at all.]

[Senpai, Ive said this before, but that person sounds seriously dangerous shouldnt you avoid owing her anything?]

[No, I told you, shes someone youre connected to well, its not really about owing her. Its more like shes eaten me so many times that Im just getting her to repay that debt Anyway! Kaito, were heading out right now! Are you ready to go!?]

[No, this is the first Im hearing of it, and I literally just woke up.]

Somehow, it suddenly turned into going out somewhere, but I just woke up and only had one cup of coffee!

[Hm, then, well go get ready quickly.]

[Ahh, so us going is already decided. But you said something about proactive seriousness, where are we even going? Depending on the place, what I need to prepare will change]

[An onsen!]

[What does an onsen have to do with seriousness?]

[No, theres no relation between onsens and seriousness at all. What are you even talking about?]

[Senpai, can I give you a slightly strong slap?]

[C- Calm down! This was a calculated choice. The reason I picked an onsen as the destination is because an onsen chapter is coming up!!!]

To repeat, I just woke up and Im already having this conversation The fact that I didnt pull out my piko-piko hammer means Im being pretty kind here.

[I dont really get whats going on, but is this like going to an onsen ahead of the onsen episode? Kind of like scouting it out?]

[Youre close but not quite. By personally carrying out an onsen chapter myself, Ill build up resistance to onsens and reduce the damage. And theres also a reason I invited you at this specific time!]

[Its early morning, what kind of reason is that?]

[Fufufu, by heading to the onsen town this early There wouldnt be enough time for an extra chapter that includes a mixed-bathing event to be written. Even if its extended by one or two chapters like before, we wont reach the bathing scene! In other words, I can gain onsen resistance while avoiding any lovey-dovey events, a perfect plan!!! Fuhaha, quite unfortunate huh, Mixed Bath King! You wont get a chance to activate your unique skill!]

[Just to ask, who exactly are you calling the Mixed Bath King? Depending on your answer, I might get mad.]

[Well, I mean, if youve had mixed baths with all your lovers and several others too, doesnt that make you one?]

[.]

A completely irrefutable argument. If youve experienced mixed bathing with a double-digit number of women, being called that might be unavoidable. But still still

[But somehow, being shut down by you with a logical argument doesnt sit right with me so Im going to hit you once with my piko-piko hammer.]

[Why!? B*stard, at some point, you started treating me like Alice and Tre, as someone you can handle roughly, didnt you!?]

Makina : [I dont understand why is everyone making me build the onsen town? Also, the title already confirms that Serious-senpais plan is going to fail.]
