From the author who wrote A Silent Voice, you can expect a lot of tears to be shed in this story.
- Whenever the people who Fushi interacted with die and see their version of a perfect life, they look around in confusion and ask where Fushi is, only to realize that they are dead.
- When the nameless boy realizes that his tribe had been essentially wiped out by the snowstorm and sees a sign that says "turn back", his cheery optimism finally fails him as he breaks down in the snow and begins to cry.
- When Fushi looks at him and notices the boy doesn't look well, his face looks extremely worried.
- Just as he slowly succumbs to his fever, he talks to Fushi and tells him with a smile to never forget him. Even until the very end, the boy never stopped smiling as he passed peacefully in his sleep.
- Fushi even tries to move his body when the boy fell out of his chair, but didn't move.
- The fact that the wolf corpse Fushi finds in the snow is actually Johann, makes it more heartbreaking when the boy sees Fushi, believing his furry companion who was lost for so long had finally returned.
- The boy sees his afterlife, which has Johann, his village, and he happily asks if they had "fruit".
- March's dream of growing up to become a mother is essentially dashed when she's chosen to become the annual sacrifice to the rampant bear spirit.
- In the afterlife, we see March's wish come true as she's shown as a young woman who's eager to raise her children.
- March trying to stop Parona from committing suicide as she holds March's lifeless body.
- Gugu being shunned by the townspeople once they see his deformed face underneath his math. When a man hires him to work, one of the man's sons wakes him up by throwing water on him and tells him to straight up leave, calling him an inconvenience and a monster. It's hard not to want to give Gugu a hug when he's constantly ostracized by the people around him for something that was beyond his control.
- Gugu testing Fushi's other abilities and the two realizing that Fushi can conjure items he has touched or tasted before from his body. Gugu takes it a bit too far, cutting Fushi with a knife and burning him with a piece of firewood. While Fushi can heal quickly, Gugu scolds Fushi and tells him it's for his own good, Fushi at first looks surprised and close to crying.
- Gugu crying when he thinks Fushi truly died after being swallowed by the Nokker Bear. His words: “I’m sorry Fushi. For being such a powerless brother.”
- Fushi feeling pain when fighting the monster for a third time, but realizing he hadn't sustained any injuries yet. When he suddenly takes on Gugu's form mid battle, he cries out in anguish, heaving out balls of fire and vehemently denying that Gugu was dead.
- Fushi going back to the old man and woman who looked after him and Gugu for the past years to tell them that Gugu had died.
- Gugu, realizing that he had died, attempts to comfort his surrogate family with a hug as he watches them cry.
- Rean running to see Gugu, whose form Fushi had taken, and telling him she loved him.
- It's shown that despite how the others tried to hide it, Rean knows Gugu is dead, but carried on with a smile. As Gugu leaves, she promises to wait for him and when he returns, they'd go pick flowers like he promised.
- Afraid of his loved ones getting hurt or killed Fushi tries to tell Pyoran to go back to the medicine man's home or leave him alone. She stubbornly refuses, even going so far as to bite Fushi. He finally relents and makes her promise not to die, Pyoran understands Fushi's reasoning for acting the way he is and promises him that she won't.
- Doubling as Nightmare Fuel: eventually Fushi, the Immortal, gets to see Pyoran die. Of old age, going senile and developing Alzheimer-like symptoms turning the once active and lively old woman into a shell of her former self, sullen and needy until Pyoran herself, in one of her few moments of lucid thinking, begs the Man in Black to reincarnate in a new form that will be useful to Fushi, knowing that her frail and old body will be of no use to him in his struggles. Fushi is utterly devastated and scarred from the events.
- Fushi accidentally kills a mole that was digging nearby in his wolf form, and after he realizes what he's done he gives a heart-breaking apology saying he didn't mean to.
- In his gladiator match Fushi tries to find a form strong enough to beat his opponent and while he recalls March being shot with an arrow, he takes the form of Parona. Fushi is horrified afterwards and wonders why Parona would take her own life.
- The man in black comments that "Parona of the Ninanna... it is good she died quicker than I expected", to which Fushi in Parona's form looks at the man with disgust at his apathy towards life.
- What's worse, it was because Hayase was taking Parona's face from her and killed her in the process.
- Every time Fushi learns that someone he thought was alive had died.
- Fushi meeting an older Tonari, but not recognizing her until she had just passed.
- Chapter 68 reveals that Fushi might be able to being the dead back to life. It's possible he could have brought his friends back the entire time and he's been suffering for nothing. What's worse, Bon hides this.
- Fushi getting a doll from town and while admitting it was the prettiest thing she'd ever seen, she knew that March would have liked to see the doll.
- Bon sets the doll down and briefly talks to March before leaving the tent. March's spirit is kneeling in front of the doll, watching Bon leave as her hand stretches out towards it.
- After Tonari saves Fushi, she's dying of internal injuries from the Nokker's tendrils. Her last wish is to see the faces of the people Fushi has met, and he obliges. The Nameless Boy, March, Parona, Shin, Gugu, Old Booze Man, Rean, Nand, Oopa, Mia, Uroy... Fushi visibly starts losing his composure, as being able to take their forms only confirms their deaths.
- After the deaths of March, Gugu, and Tonari, each are shown visions of a happy life they could live with their loved ones, but remembering their bond with Fushi, they turn around to see him grieving their deaths as the images of their loved ones begin to crumble away. This is sad enough on its own, but later chapters reveal through conversations between Bon and his Spirit Advisors that when people die, they are normally taken to "Paradise," but those reluctant to move on instead become lingering spirits, able to see the world but unable to interact with anyone without a particular aptitude like Bon. The images of Tonari and Gugu holding a grieving Fushi become even sadder when you realize that they've given up eternal happiness to stay by the side of someone who can't even see them.
- Fushi realizing he has to let his friends go their own paths. He's terrified of everyone leaving him, best represented by a delusion he has of March saying goodbye to him in progressively older bodies until she's a withering old woman. While it's understandable that he wants something to hold on to over his immortal life, seeing his companions struggle to keep up with the modern day simply because Fushi wants them near him hurts more. Giving Gugu tickets to fly to his home country was one of the first painful steps he took to maturity.
