My encounters in the Friendship City were very fruitful. It was great that I got to know Olivia-san and met Kaori-san, who is also from that world.

  When I talked to Aoi-chan and Hina-chan about her after we returned, they were also very eager to meet her, so I decided to take them to her restaurant again next time.

  A few days after returning from the Friendship City, I was having lunch with the trio of Lilia-san, Luna-san, Sieg-san and my two kouhais, Aoi-chan and Hina-chan.

  Well, while I was chatting happily over a meal with Sieg-san and Lilia-san, who happened to have time, and Luna-san who was in attendance with their permission…… when the door to the dining room opened and Anima entered.

  [Anima?]

  [Master, I apologize for interrupting your meal. Actually, I received a letter from Lillywood-dono.]

  [Eh? From Lillywood-san? Not just a hummingbird, she went out of her way to send a letter?]

  [Yes. So, thinking this might be important, I brought it to you.]

  This is really unusual. I mean, wouldn’t this be the first time she sent a letter? If she needed something from me, sending a hummingbird would have sufficed, and in fact, that was how we handled things in the past, but the fact that she went out of her way to send me a letter suggests that there may be a reason for it.

  Then, slightly curious about it, I opened the envelope Anima handed to me……


  [……Unnn? Errr……]

  [Kaito-san?]

  [It says something about an invitation to a tea party……]

  Inside the envelope was an invitation made of beautiful, luxurious paper and a letter from Lillywood-san. The letter included a schedule and an explanation of the tea party, concluding with an invitation to come if it would suit my schedule.

  [A tea party? Is it a large-scale one that she would need to prepare this invitation?]

  [Hmmm, it doesn’t say that much about it, but the location seems to be Lillywood-san’s castle in Yggfresis.]

  The question Lilia-san asked while tilting her head is quite reasonable. With her going to the trouble of sending an invitation, I also think that it won’t be just a small gathering.

  [……A tea party on a scale where they had to prepare invitations. It’s hard to think that invitations were made only for Kaito-san, so there should be other guests as well…… Hmmm, Luna, do you have any ideas about what this may be?]

  [At this time of the year…… I wonder if something happened?]

  Lilia-san’s question also made Luna-san tilt her head. If the tea party was hosted by Lillywood-san, it must have been quite famous, but the fact that neither of them had any idea about it suggests that it’s not a regular event?

  While I was thinking about this, Sieg-san, who had her hand on her chin, seemingly thinking about this matter too, spoke.

  [……Could it be perhaps, for the after-party of the “Harmonic Symphony”?]

  [Ahh, I see, you’re right! Come to think of it, this is a year when the Harmonic Symphony is held.]

  [I’ve heard rumors about it. That after the Harmonic Symphony, there will be an after-party that only World King’s subordinates and those specially invited can attend……]

  [ [ [ Harmonic Symphony? ] ] ]

  Lilia-san and Luna-san seemed to agree with Sieg-san’s words, but Aoi-chan, Hina-chan and I tilted our heads, not really understanding what was happening.

  [Errr, Alice-sama had mentioned it a little at the time when Kaito-san’s birthday was held, but for Spirits and Fairies, singing is an important way to communicate with nature. And once every three years, in the largest nature city in the Demon Realm, Yggrfresis, an event called the Harmonic Symphony is held.]

  [Does that mean it’s a festival?]

  [No, it’s a little different. There are no stalls around, and singing and dancing are the main events…… Putting it in very simple terms, I guess it’s like a city-wide concert?]

  From Lilia’s words as she explained the event, it sounds like a considerably large-scale music competition.

  [The Harmonic Symphony is one of the biggest events in the Demon Realm, and it brings together the Seven Princesses, who usually don’t gather, in one place.]

  [Heehhh…… That sounds like a fun event. Were normal people able to participate in it?]

  Hearing the additional information Sieg-san gave, Hina-chan asked with a happy expression on her face. Aoi-chan also seems quite interested in this, as she paid attention to the conversation.

  Somehow, I kinda imagine Hina-chan liking dancing and uplifting music, while Aoi-chan feels more like someone who appreciates calming music like one of those performed by classical musicians.

  [The Harmonic Symphony is open to everyone. Mother once took me there when I was a little girl, and I remember it was pretty lively with singing and dancing everywhere.]

  When I heard Luna-san’s words, I also thought that it sounds like a fun event…… but wait a moment there. The conversation shifted to the Harmonic Symphony, but the invitation I received wasn’t for that event, but to a tea party.

  ……Since this was an invitation to an event unlike the Harmonic Symphony, which was open for the public, I feel like this tea party is quite a big deal……
