Chainsaw Man chapter 108 sends fans theorizing about Yoru's older sister

In Chainsaw Man chapter 108, we saw Asa making use of Yoru's War Devil powers to make a sword out of her uniform, which she moments later used to cut Yuko into pieces. While Asa did want to stop Yuko, she did not want to kill her, and thus was willing to accept help from a stranger when she offered help.

However, as the stranger approached Asa and Yuko, she revealed herself to be her older sister. As Asa herself didn't have any siblings, the stranger may have implied being Yoru's older sister. Thus, fans were left theorizing about the identity of Yoru's older sister. Who could it be?

After the release of Chainsaw Man chapter 108, fans were adamant that Yoru's older sister was one of the Four Horsemen. The Four Horsemen is a group of four individual powerful devils who once collaborated to fight against the Chainsaw Devil. These four devils may be stronger or at par with the primal fears, given how the Darkness Devil was able to cut Makima's arms.

In Chainsaw Man part 1, Makima revealed the Four Horsemen to be Control Devil, War Devil, Death Devil, and Hunger Devil, all of whom were capable of remembering the devils who had been devoured by the Chainsaw Devil. Makima herself was the Control Devil.

One way to identify the Four Horsemen was through their eyes, which were yellow with multiple red rings within them, as seen in Makima's case. The same could be observed in the case of Yoru and her supposed older sister, thus fans were adamant that the stranger was the third Horseman.

Considering that the Control Devil has already been reincarnated in the form of Nayuta, and the War Devil has currently claimed Asa Mitaka's body, the third Horseman has to be either the Death Devil or the Hunger Devil.

The majority of fans have concluded that the third horseman of the apocalypse who was introduced was Death Devil, given how war is considered to be a major cause of death, and thus both War Devil and Death Devil could be related to each other.

One fan even pointed out that the devil was confident in her ability to save a dying Yuko, which could be a hint towards her control over death.

However, another fan pointed out how Yoru's older sister could also be the Hunger Devil, given how her earrings looked like the scales used by the Famine Devil in mythology. Given how famine is biblically the Third Horseman of the Apocalypse, it is fitting that the Hunger Devil could be revealed to be the third horseman in the manga as well.

One fan even chose to look into mythology and compare the Four Horsemen of the Apocalypse with the one that had been introduced in the Chainsaw Man manga.

When comparing the devils to their subsequent Horseman, it is quite evident that the third Horseman who has been introduced in the manga is the Hunger Devil.

Also, given how death is a primal fear, it being introduced this early in the manga does not sit well with the future of the series. Death being something everyone fears should be the strongest Horseman, and thus could act as the final antagonist in Chainsaw Man.
