Drawing on over 30 years of experience with guitars and bands since my high school days, I specialize in music-related articles and have handled many feature pieces to date. While my tastes lean toward genres like hard rock and heavy metal since I first picked up the guitar, I make a point of listening to a wide range of styles, both Japanese and Western, on a daily basis. I began working as a freelance writer in 2018. I hold a Web Writing Practical Certification, and in addition to writing, I’m also studying video editing. In my private life, I’m raising an elementary school child and stay active while supporting their extracurriculars, such as parkour and dance.

Too strong it’s sad… What Kokushibo Yoriichi’s quotes teach about true strength (11–20)

Someday, the children who are yet to be born will surpass us and climb to even greater heights.Yoriichi Tsugikuni 'Demon Slayer'

A famous line spoken during a conversation with his older brother, Michikatsu Tsugikuni: “Someday, the children who will be born after us will surpass us and climb to even greater heights.” This quote highlights the contrast between the brother, who believes they themselves are the strongest, and Yoriichi Tsugikuni, who places his hope in the future.

For Michikatsu—who wants the strongest, his younger brother, to acknowledge him as the only one who can stand at his side—it must have been a message that made him painfully aware of the overwhelming gap between them.

It’s a memorable quote that conveys how differences in talent can lead to differences in worldview.
