Author’s Comment
"This has happened a lot lately, but I keep hearing “my kid is a big fan of your manga” from mangaka or celebrities that I loved as a child. Every time I hear those words, I almost cry, thinking “I am so glad I became a mangaka.” When I think about how I was able to give something back to the people I loved, and how I played my part in the manga system that ties children together, it makes me so happy."
