Demon Slayer: Kimetsu no Yaiba Hashira Training Arc Episode 4 Review

Demon Slayer: Kimetsu no Yaiba Hashira Training Arc Episode 4 Review

Serpent, Wind, and Mist

Demon Slayer: Kimetsu no Yaiba Hashira Training Arc Episode 4 was a bit better than Episode 3. I guess we technically got a bit more action in Episode 3. But the action in Episode 4 was cooler. We got to see three Hashira fighting each other.

However, I need to make a correction to something I said in last week’s review. I assumed that Iguro and Shinazugawa would be fighting each other with real swords. That turned out not to be the case. They used wooden swords for their duel.

But why did I think they’d use real swords? And why didn’t they? I assumed they were trying to awaken the mark on each other. And, as far as we know, the best way to do that is real combat where your life is on the line. It turns out, they just wanted some training, hence the wooden swords.

Training the random demon slayers is good and all. However, that doesn’t really serve as training for the Hashira. They’re not getting any stronger by teaching the demon slayer NPCs. That’s why Iguro, Shinazugawa, and Tokitou decided to train amongst themselves at night.

When we first learned that Tokitou was going out in the evenings, I assumed he was patroling for demons. And when we found out what he was actually up to, I thought Tanjirou would show up to train with them. It would have been cool to see a 2v2 duel.

But it looks like that wouldn’t have gone well for the Serpent and Wind Hashira. They teamed up against a solo Tokitou, acknowledging his skill as a prodigy of the sword. I was surprised to see those two do that. And I was even more surprised by them hanging out afterward.

Tokitou’s Training

The standard issue demon slayers aren’t big fans of all this training under the Hashira. Compared to them, the Hashira are superhuman. What a Hashira believes is normal for a training session is way beyond what the average demon slayer can handle.

We saw this during Tengen’s episode and again during Tokitou’s episode. But the Hashira aren’t being hard on the demon slayers for no reason. And it’s not even because they think the demon slayers will be useful in future battles against the demons. It’s because they don’t want the demon slayers to die.

Something we’ve learned over the course of this series is that all of the Hashira want to protect people. It’s sometimes hard to see that. But it’s true. To most of the demon slayers, Tokitou seems emotionless and like he doesn’t care about what happens to them. That’s not the case.

This is also the case for Shinazugawa and Iguro. They do not seem like friendly or nice people. However, at the end of the day, they’re demon slayers for one reason. They want to save people by destroying the demons once and for all.

We got to see this nicer side of Shinazugawa a bit in the previous episode during his brother’s flashback. And, sure, we haven’t seen anything about Iguro that explicitly shows that he’s actually nice. But, from how these two interact with Tokitou, that seems to be the case. These three seem harsh, but they actually want to save everyone.

I think Tokitou did a good job of illustrating this to the demon slayers in his care. Yes, he outright told them he didn’t want any of them to die. But he also tried to make them view this training as vital to their survival.

The Paper Airplane Hashira

I wasn’t a huge fan of the end of Episode 4. I don’t mean the post-credit stuff with Kanroji; that was fine. What I didn’t like was the paper airplane competition Tanjirou had with Tokitou. I get the point of it. But I didn’t feel like it added anything.

So, what was the point? Tanjirou knows that Tokitou is a nice guy and is only looking out for the other demon slayers. But the other demon slayers feel that Tokitou’s being too hard on them, so Tanjirou wants him to be nicer to them.

If Tanjirou can beat Tokitou in a paper airplane contest one out of ten times, Tokitou will do what he says. However, this isn’t the only thing Tanjirou was after, which is good because he failed to defeat Tokitou. Tanjirou also wanted to show the demon slayers another side of the Hashira.

Everyone views Tokitou as someone who doesn’t like to have fun. He’s very by-the-book in everything he does. His swordsmanship, training, and interactions with his students are all “emotionless” and by-the-book. But when he’s interacting with Tanjirou, we see a different side of Tokitou.

This is the real reason why Tanjirou challenged Tokitou to the paper airplane competition. It’s why he was asking Kanamori what Tokitou’s hobbies were. He wanted to challenge Tokitou to something he liked so the other demon slayers would see him having fun. They’d see him as a normal person, not some scary, emotionless monster.

The thing is, I’m not sure this part of the episode was all that necessary. Tokitou already gave his little speech about not wanting any of the demon slayers to die. Why couldn’t that have been what showed the other demon slayers that he has feelings?

Final Thoughts

What do you think of Demon Slayer: Kimetsu no Yaiba Hashira Training Arc Episode 4? Would you have preferred if Tanjirou teamed up with Tokitou to fight the other two Hashira? Which Hashira’s training do you think will be the hardest for the average demon slayer? And did you like the paper airplane competition at the end of the episode?
