After the massacre where his family perished, Tanjirō decides to take his sister into the care of Dr. Tamayo.
Years later, he returns to Nezuko, to take her to their new home, where he could keep her safe.

Most of them are too busy deciding how they're going to divide their inheritance. Naive children, his will is already written, you won't be able to spend anything unnecessarily. He's made sure to leave enough for many more generations. But right now, he feels weaker and weaker. As a child, he never thought he'd make it. He'll die of old age, not from the curse. What a joy.

"You know the answer, why do you keep asking?" Yushiro doesn't like drama or embellishments, he had made that clear for so long, but his voice, Kiriya could swear for a moment that he hesitated.

Summary
— Не знаю, — тихо, почти шёпотом, — Я и сам не знаю, кто он для меня.
Пауза. Лампа тускло горит, отражаясь в запотевшем стекле. За окном - ни луны, ни звёзд, только серая пустота.
— Но когда я слышу его имя… — он произносит это с трудом - так, словно каждое слово даётся через боль, оставляя ожог на языке, — Внутри всё будто вспыхивает. И тянет туда, даже если там - гибель. Если Солнце и Луна обречены лишь смотреть друг на друга издалека… То затмение - это всё, что нам позволено.

She was startled by a knock at the door. Nezuko's intuition had always been strong. She couldn't remember the last time someone walked up to their house without her noticing.She automatically looked to Tanjiro. Her brother sniffed the air with a small frown on his face. But he put on a smile as he got up to open the door.
