Jigorō Kuwajima’s quotes resonate deeply. Life lessons learned from Demon Slayer (1–10)
Don’t cry!! Don’t run away!! There’s no meaning in such actions!!Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
“Don’t cry! Don’t run away! There’s no meaning in such actions!” is the powerful scolding line Grandpa delivers to Zenitsu in Volume 4, Chapter 33.
When Zenitsu fled during training and climbed a tree, refusing to come down, his master admonished him, saying that behavior was pointless.
This quote teaches the importance of facing difficulties without running away, resonating as a strong message that makes readers reflect on the value of challenge and effort.
In everyday studying, work, or sports, remembering these words can give us the courage to take a step forward instead of escaping.
Calm down!! Zenitsu, you have talent…Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba
The line from the iconic scene in Demon Slayer: “Calm down! Zenitsu, you have talent…” is addressed to Zenitsu, who, during training, climbs a tree and wails, “I can’t do it.” Gramps recognized the talent that Zenitsu himself couldn’t see and tried to encourage him with those words.
However, right after that, lightning strikes the tree directly, and Zenitsu falls.
While this scene may seem to depict Zenitsu’s unreliability and helplessness, he ultimately grows to the point of refining the First Form.
Gramps’s keen insight had perceived Zenitsu’s latent potential from the very beginning.
If you can only do one thing, master it completely.Jigorō Kuwajima, Demon Slayer: Kimetsu no Yaiba

Of the six Thunder Breathing forms, Zenitsu Agatsuma could use only the First Form.
Jigoro used to praise him, saying, “If you can master even one, that’s more than enough,” but in the past he apparently blew his top over Zenitsu being able to use only one.
Even so, Zenitsu threw himself into the harsh training, yet still managed to master only the First Form.
These are the words Jigoro said to Zenitsu then.
Just as those words suggested, Zenitsu pushed a single skill to its absolute limits and created techniques only he could use, such as Thunderclap and Flash and Thunderclap and Flash: Sixfold.
He even unleashed the strongest Thunder Breathing technique against Kaigaku after he became a demon.

“Follow Kaigaku’s example! Be like your senior disciple!!” appears in Chapter 145 of Volume 17 of Demon Slayer: Kimetsu no Yaiba.
It’s in the scene where Zenitsu faces Kaigaku, who was once his senior disciple.
Kaigaku declares, “I’m special.
I’m not like you,” and unleashes Thunder Breathing, Sixth Form: Rumble and Flash.
In that moment, Zenitsu recalls the words of his master, the old man, which fuels his growth and courage.
This quote is more than simple encouragement; it underscores the importance of effort and resolve, leaving a lasting impression on readers by offering lessons and bravery.
