I’ve noticed that Demon Slayer is widely considered one of the most beautifully animated anime series in recent years. What really stands out is the animation quality – it’s truly amazing. Plus, the show adds some scenes that aren’t in the original manga, which actually makes the story even better. Most fans agree it stays very true to the source material, too.

Even a popular anime like Demon Slayer isn’t a perfect adaptation of its source material. While the main storyline remains intact, the show sometimes leaves out details that would have given us a deeper understanding of the characters and their motivations.
Tanjiro vs. Spider Demon (Father)
The Mount Natagumo Arc is known as Tanjiro’s first encounter with the powerful Twelve Kizuki. Before his major fight with Rui, he faced several spider demons. In episode 18, a large Father Spider Demon attacks Tanjiro and Inosuke. During the fight, Tanjiro is thrown high into the air and, even using a defensive technique, crashes down hard. However, the manga version shows him landing safely and gracefully after being thrown.
It might seem like a small point, but it’s important when you think about Tanjiro’s fight with Rui. The anime shows him looking unsure and weak right before the battle, but the manga demonstrates how skilled he is with his breathing techniques. Although he’s still learning, it proves his tough training has gotten him ready. This detail also makes his win against Rui feel more believable.
A Deeper Impact from Rengoku’s Death
The first episode of the Entertainment District Arc immediately follows the heartbreaking events of the Mugen Train Arc. Before his death, Rengoku asked Tanjiro to deliver a final message to his family. Though deeply affected by Rengoku’s loss, Tanjiro feels obligated to honor his request. The episode opens with Tanjiro already traveling to fulfill this promise, shown continuing his journey despite being injured. Along the way, Senjuro notices his pale appearance and asks if he’s alright.
The anime showed Tanjiro’s sadness after Rengoku’s death, but the manga portrays it even more effectively. The manga emphasized a feeling of frantic urgency; Tanjiro left so quickly he didn’t even bother to pack his bedding, highlighting how consumed he was by grief and how it made him forget his usual routines. When he arrived at Rengoku’s house, he appeared completely drained, suggesting he’d run all the way there in his distress. This detail adds significant emotional weight to the scene in the manga.
Tanjiro’s Presence Left a Stronger Impression
The Rehabilitation Training Arc let Tanjiro meet the people at the Butterfly Mansion, and he really connected with them – you can feel that connection in both the manga and the anime. The manga, however, goes a step further, showing Kiyo, Sumi, and Naho openly celebrating all of Tanjiro’s successes and even crying with happiness. They first tear up when he finally breaks the gourd, something they helped him train for, and again when it’s time for him and his friends to leave.
The same holds true for Kanao. While the anime shows her being impressed after talking to Tanjiro, the manga goes further – she’s also shown tripping, revealing a clumsy and relatable side that wasn’t present in the anime. These moments highlight Tanjiro’s knack for connecting with people through his genuine kindness. This added scene with Kanao can also be interpreted as the beginning of her developing romantic feelings for him.
Zenitsu’s Affection for Nezuko is Shown Better
Episode 25 of Season 1, part of the Rehabilitation Training Arc, focuses on Tanjiro, Inosuke, and Zenitsu working hard to improve their skills for future challenges. We also see Tanjiro and Inosuke getting their swords fixed after the fight on Mount Natagumo. A funny moment happens when Inosuke immediately damages his new sword, and Tanjiro steps in to calm down an upset Kanamori. However, the episode leaves out a scene that many fans were hoping to see.
In the manga, Zenitsu has a sweet interaction with Nezuko, who is confined in a box. He cheerfully shares details about his day, holding a flower as he talks. He mentions his friends and expresses how much he looks up to Tanjiro, promising to show Nezuko where the flower grew. Nezuko responds by scratching the box, and it’s unclear if she’s happy or not. This short, endearing moment demonstrates Zenitsu’s growing fondness for Nezuko, a feeling that develops further throughout the series.
Adding those scenes would have made Demon Slayer even better, but it remains one of the most popular anime currently airing.
Demon Slayer is available to watch on Crunchyroll and Netflix.
