Once upon a time, there was a witch named Ireina. She is on a carefree journey, wishing for encounters and farewells, and hoping to reunite with important people in her life. This time, she will meet an immortal witch, self-proclaimed citizens of a developed nation, a witch of ink, a fake witch skilled in sewing, a female spy who dislikes coffee, and sisters from a former legitimate knight order. There are also the cat tribe girls working in a café. And then, there is a timeless encounter with a girl with black hair, connected by fate... What will the meeting between Ireina and the girl bring to this world? "Surely, this is a long, long repayment of kindness." When the broom star races across the night sky, a slightly sad miracle will visit the girls.
