I think there are these high-rated, niche anime that can be watched in one day:

1. "Big Sword"

Plot summary

Since ancient times, demons have invaded the human world, transformed into humans and made a living by devouring human internal organs. Humans, who are helpless against the demons, can only turn to female warriors carrying giant swords for help.

Because warriors gain superhuman strength due to the blood and flesh of demons mixed in their bodies, humans also regard them as aliens. On the one hand, they rely on them to kill demons, on the other hand, they fear and reject them. And called them "Claymore (Great Sword)".

When the appearance of demons broke the peaceful life of an ordinary mountain village, the helpless village chief had no choice but to turn to the Big Sword Organization for help. A soldier with a cold face accepted the commission and came here, thus kicking off this magnificent story.

2. "Death Note"

Plot summary

Short story

After the death god Ryuk lost the Death Note, he was killed by a 13-year-old middle school student. Kyotaro picked it up and used it as a diary. He accidentally killed five classmates who had bullied him, believing that the notes were true. The horrified Jintaro used the death eraser given by Liu Ke to erase the names on the notes, resurrecting the five people. After learning that the five people were resurrected, the two police officers who investigated the matter rushed to the school to investigate and inquire, but they were killed together with the five resurrected people. Jingtaro asked Liu Ke and found that another notebook of Liu Ke was missing, and thought of Miura who was also bullied by the five people and questioned by the police. Finally, Kagetaro found Miura, used an eraser to erase the names of the seven dead people, and then handed the second notebook to the two resurrected policemen.

In front of the police, Jingtaro asked Miura to kill himself as an experiment, and then erased his name with an eraser and resurrected him to make the police believe him. Afterwards, the four burned the notes and kept them secret. Seven years later, Jingtaro grew up, kept the first notebook, and published the story of the Death Note as a novel
