Mortalを考える 泣いてもいい? (Tankobon Hardcover)

The artwork is so delicate and expressive — I wonder what inspired the visual choices to evoke emotion without overwhelming young readers.

It’s rare to see a children’s book handle such heavy themes with tenderness. Did the emotional tone resonate differently with different age groups?

The message feels both comforting and profound. I’m curious if this theme came from personal experiences or a particular philosophy.
