A vast plain spreading across the Demon Realm. Among the Demons that inhabit the plains, there is a particularly huge group of Emperor Bulls. Each one of them standing over ten meters tall, they would charge at enemies in a line.

  The Emperor Bulls reigned supreme over the plains and even the dragons were no match for their hordes…… but that’s only if they’re against monsters.

  [10, 20…… This should be enough.]

  Zwei, a member of Underworld King’s family, is currently “counting the number of Emperor Bulls they have decapitated and bled out.

  She would normally be busy running Underworld King’s territory, but she had put off all her work to participate in this urgent situation.

  [Neun, Vier…… Please take this to Ein immediately. I’m going to go catch the next ingredient, Tyrant Fish.]

  [Alright.]

  [Unnn! In that case, after we bring them to Sister Ein, we’ll go to the lake in the Ancient Forest.]

  [Yes, I’m counting on you.]

  After seeing off Neun and Vier, who were carrying a large number of Emperor Bulls as she instructed, Zwei headed off to her next destination at super speed.

  At the same time, in the largest forest in the Demon Realm that exists near the center of the Demon Realm, there stands Isis and Lillywood.

  [……Lillywood…… Please.]

  “Yes, I heard about how Razelia would provide the vegetables, while we would bring fruits…… My followers, I would have to trouble you for a bit.”


  Nodding to Isis’ words, Lillywood held out her hand to the forest, and a large amount of fruits immediately appeared on the vast amount of trees. The fruits then immediately pops off the tree, and pulled on the ground by gravity…… but stopped in midair.

  [……Kaito…… likes…… ripple fruits.]

  “I see, then we’ll prepare some of them too.”


  [……Unnn…… it would be great…… if Kaito…… gets delighted with this.]

  After securing a large amount of fresh fruits, Isis and Lillywood repeated the process as they went around the forest, harvesting one set of fruits after another.

  In the castle of the Underworld King Kuromueina, Ein, who was in charge of the kitchen, and Shalltear, the Phantasmal King, was there.

  [……Kuro-san has already left huh?]

  [Yes, she needs to prepare presents and secure a place for us to celebrate. As expected though, she doesn’t have that much time to prepare, so Kuromu-sama apparently went to ask for God Realm’s cooperation.]

  [Then, since the ingredients are arriving, I guess we’ll just do our own things huh…… We would be preparing a couple of cakes and other dishes, but would this really be alright?]

  [You must be kidding, right…… You and I are going to team up with cooking. How can we not make it in time?]

  [I guess you’re right.]

  With two of the most skilled cooks in the Demon Realm…… no, in the world working side by side, they faced the mountain of ingredients brought in by others.

  With each hand moving with a speed that it leaves sound behind, and yet, with a precision that seemed like they could easily pierce a thread through the hole of a needle, they cooked an overwhelming amount of food.

  [……Speaking of which, Shalltear. Why is it that your clone is the one cooking here?]

  [……The main body is flirting with Kaito-san. I also wanted to have some surprise at the birthday party, so I was keeping Kaito-san occupied in the miscellaneous goods store until everyone’s ready.]

  [I see.]

  Finishing several dishes at a frightening speed while the two conversed with each other, the people in charge of preparing the venue began bringing them into the venue.

  It’s not only the Demon Realm that has become busy. There were people who were also busy in the God Realm.

  [……Why? Why are we the ones in charge of “constructing a venue”……]

  [Of course, it’s to make Kai-chan’s birthday the best one ever! If we don’t make it soon, since “we still have to carry it to the Human Realm”, we won’t make it in time!]

  [She’s right. If you have time to talk, you should just get your hands moving, God of Time and Space. If there’s even one flaw in our work, it would be a disgrace to Shallow Vernal-sama’s reputation.]

  [Uggghhh, I know!]

  The Supreme Gods Chronois, Fate, and Life…… under Shallow Vernal’s instructions, were currently building “a castle that will be used as the venue”.

  Honestly speaking, it would have taken a moment for Shallow Vernal to create it, but saying that she had other things to do, she only gave them instructions before leaving.

  As a result, construction was being done by the joint cooperation of Chronois, who can work at super high speed, Fate, who can manipulate probabilities and greatly lessen the work they needed to do, and Life, who can generate an inexhaustible supply of labour.

  And as for Shallow Vernal…… She was currently facing the Earth God, Eden, in the Sanctuary.

  [……I believe our interests are perfectly aligned, correct?]

  [Positive.]

  [Well then, we don’t have a problem with that matter, right?]

  [Again, Positive. My Child, First Priority, Restriction, Pledge, Limited, Release, Approve.]

  As the interests of the two Gods of worlds perfectly aligned, they have unconditionally joined forces with each other. In a sense, it could be said that the two people who shouldn’t be working together at all have joined forces…… but unfortunately, Kuromueina, who can stop these two from running amok, is busy elsewhere and currently isn’t here.

  And so, on that day, the world’s common sense would be overturned once again.

  The Symphonia Kingdom is the planned location for Kaito’s birthday party. And being in the midst of such a situation, the royal castle was also in a state of chaos.

  [Father! The nobles who heard about the party expressed their wish to attend……]

  [No! With Miyama-kun’s personality, he will not be pleased. Decline all those who haven’t directly spoken with Miyama-kun!]

  The king, Ryze, immediately made his decision and replied to Orchid’s words as he rushed into his office. Ryze still had to entertain the guests from Archlesia Empire and Hydra Kingdom, so his workload had increased to an extraordinary degree.

  It was a critical moment for Ryze, but also a fortuitous one.

  Kaito’s birthday party…… It was said that the venue would be prepared by the God Realm, but the event would take place in Symphonia Kingdom.

  Such an event would inevitably bring him a lot of work to do, but in the end, this event will bring tremendous benefits to the country.

  At the same time, in order to ease the burden on his beloved little sister, Lilia, Ryze is exerting effort greater than ever before.

  Unaware that a birthday party of an unprecedented level was about to be held, involving the cooperation of the three realms, Kaito was leisurely drinking tea at Alice’s miscellaneous goods store.

  [Ahh, Kaito-san. I think we’ll be able to get the birthday party ready in time, so please look forward to it. Ahh, don’t worry. I’ve limited the number of participants to Kaito-san’s acquaintances.]

  [Really? You don’t really have to bother yourself with that though…… Even so, could you tell my thanks to your subordinates?]

  [Roger that.]

  Currently, what Kaito is imagining is a small party held only by his family and friends. What he didn’t expect though was that for his sake, a new castle was being built as his party’s venue……
