In Shiga Prefecture, east of Kyoto Prefecture, Takanashi Rikka was originally quite interested when her surname was mentioned by the mysterious person.
After all, as the mysterious person had said, Takanashi was such a niche surname that basically all people with the surname Takanashi were related by blood to some extent.
Even if you traced it back to their grandfather's generation, there was definitely a connection.
It was just that by their parents' generation, for various reasons, they had scattered to various parts of Japan after growing up.
Of course, these were all things Takanashi Rikka had heard from her older sister when she was a child.
Therefore, when she saw the mysterious person write in the diary that among the people with the surname Takanashi, there was also a vampire and someone who had been reincarnated into another world as a saintess, her eyes lit up.
She was even thinking about which of the Takanashis she knew might be a vampire, and who might have already been reincarnated and gone to another world.
Of course, what she was looking forward to even more was that she felt that as long as she insisted on reading the diary every day, she would sooner or later be able to truly break the seal of the Tyrant's Eye.
It was just that when she saw the content that followed, when the mysterious person mentioned that a certain Takanashi might die in a plane crash, she immediately became nervous.
Although she was a chuunibyou, she was, after all, just a girl who had just entered high school.
Having lost her mother in her childhood and her father three years ago, the current Takanashi Rikka had already developed a considerable trauma regarding the departure of her relatives.
Therefore, after the mysterious person's reminder, she immediately ran out of her room and asked her sister, who was watching TV, if their Takanashi family had such a relative who had been married three times.
Hearing her own sister, who was a chuunibyou all day, not being so chuunibyou for once, but the question she asked was so strange, Takanashi Tōka felt a bit of a headache.
What do you mean, a Takanashi who has been married three times and has three daughters? Is that how you talk about your own elders?
However, seeing that her younger sister's expression was quite serious, Takanashi Tōka still carefully recalled the family situation of their relatives.
After just a moment of thought, Takanashi Tōka found the person Rikka might be talking about.
"You're probably talking about Uncle Shingo. He works in Tokyo, and for various reasons, he has indeed been married several times. Speaking of which, his eldest daughter seems to be two years younger than you. She should be in the second year of middle school now."
"When father passed away, he had brought his wife and his little daughter, who had just been born, to attend the funeral. He even thought of taking us to live in Tokyo. But because his family was already raising several daughters, I rejected him in the end. But he did take good care of us at that time... Why are you suddenly asking about this?"
Listening to her sister's explanation, a somewhat familiar face began to flash in Takanashi Rikka's mind.
So it was that uncle?
Thinking that he seemed to have brought her a lot of foreign candy when she was a child, Takanashi Rikka couldn't help but clench her small fists slightly, feeling that she definitely couldn't let this uncle of hers die in an accident just like that.
And being asked by her sister why she had suddenly inquired about this matter, Takanashi Rikka immediately stammered that she had seen through her Tyrant's Eye that his fortune was a bit unwell recently, so she wanted to remind him that it would be best not to have any contact with air-travel-related transportation recently.
Listening to her younger sister's obviously lying appearance, Takanashi Tōka couldn't help but frown.
Her younger sister had been a chuunibyou for several years now. She could still distinguish the difference between her acting out and her lying.
So why was she lying to me?
Since a few days ago, she had felt that this sister of hers had changed a lot after entering high school.
From her original one-sided chuunibyou, it had developed onto the internet, and it seemed she had also made many new friends in her class and online.
Could it be that Rikka has met some scammer online?
Thinking this, Takanashi Tōka's expression began to become serious.
However, looking at Rikka, who was still unconsciously twirling her fingers after telling a lie, she thought for a while and felt that it was better to first go along with her words and then slowly observe what the person behind Rikka was trying to do.
"Speaking of which, after I started working, I really haven't contacted Uncle Shingo and Aunt Shizu for a year or two. It's indeed time to ask about their recent situation."
Takanashi Shingo was their fourth uncle, and Aunt Shizu was their eldest uncle's wife. [note 1]
The former worked in foreign trade in Tokyo, while the latter was engaged in politics-related work in Hokkaido. When her father had passed away, both had thought of taking the two sisters to live with them.
However, Takanashi Shingo's side had three daughters, and her eldest uncle had also passed away in an accident ten years ago. Before his death, he had had four daughters and one son with Aunt Shizu, so their invitations were ultimately declined by Takanashi Tōka.
With her younger sister's somewhat abrupt reminder, Takanashi Tōka also couldn't help but notice such a fact—her father's generation clearly had four brothers, but now, besides the fourth uncle, the others had all passed away for various reasons.
Even the fourth uncle, who was the only one still alive, had also experienced the death of his wife more than ten years ago.
Thinking of this, Takanashi Tōka, who had originally thought that Takanashi Rikka was completely talking nonsense, couldn't help but fall silent.
And while her sister was deep in thought, Takanashi Rikka, who had just told a clumsy lie, returned to her own room.
And then she naturally also saw the discussion in the group.
Tyrant's Eye: "I've already asked the Holy Priestess. That Takanashi should be my fourth uncle. I have already told the Holy Priestess in the name of the Tyrant's Eye to go and remind him. After that, it should... be able to prevent the tragedy, right?"
Because she had popped up in the group quite a few times, plus the very rich flavor of her chuunibyou, the girls in the group had long since known that the "Holy Priestess" she was talking about was her older sister.
It was just that the other girls didn't seem to think much of Takanashi Rikka's method.
After all, what normal person would believe in something like the Tyrant's Eye?
However, it was indeed very troublesome to explain the things the mysterious person had written in the diary.
Just as the few girls in the group were still giving Takanashi Rikka various suggestions, Shinomiya Kaguya, as the think tank of the group, stood out and said that she would go and help find that Takanashi in Tokyo and do her best to prevent this tragedy from happening.
What Shinomiya Kaguya was referring to here was not just to prevent the tragedy of that one Takanashi family, but to find that doomed flight through him and use this flight to gain more bargaining chips for herself in the Shinomiya family.
