does tanjiro kill muzan

In 'Demon Slayer', Tanjiro doesn't personally kill Muzan. But he does play a significant role in his downfall. Along with his team, Tanjiro exhausts Muzan out and buys enough time till dawn – the fatal weakness of all demons. As the sun rises, Muzan disintegrates leaving no trace of his existence.

Tanjiro, the protagonist of the amazingly popular anime 'Demon Slayer', doesn't kill Muzan single-handedly, but he plays a critical role in the final result. It is an entirely teamwork, an ensemble feat in which all the characters, including Tanjiro, put in their all. The ultimate goal was to keep Muzan involved until sunrise, and they manage to achieve just that. Just as daybreak arrives, Muzan finds himself trapped and without any means of escape or survival, and then he disintegrates under the sun rays.

The whole story is an impressive exercise in companionship, bravery, and self-sacrifice – genuine hallmarks consistent throughout the series.

Tanjiro, in 'Demon Slayer', does not kill Muzan in a typical one on one battle. The task is rather multi-layered and complex. Tanjiro, along with his comrades, keeps engaging Muzan in a fierce and relentless battle, which leads to Muzan getting exhausted physically and mentally. The entire operation is about running the clock down until the dawn.

When the team successfully accomplishes this, the sun does the rest of the job. As soon as the daybreak arrives, Muzan is eliminated by the sunlight, turning him to dust. So, in a broad sense, Tanjiro did contribute majorly to Muzan's end, though it isn't a straightforward kill.
