The series powerfully portrays the horrors faced by child soldiers, as Shu becomes a victim of a government that uses children as weapons.

I’ve seen a lot of shonen anime where the hero starts out full of hope, but this one really puts those ideals to the test. It’s a tough watch, honestly, because the characters are constantly thrown into a harsh, unforgiving world and forced to make really difficult choices – compromises that often feel wrong. What struck me most about Now and Then, Here and There is how honestly it depicts suffering, never turning away from the brutal realities of violence and exploitation.

Although the violence in Banana Fish can be shocking, the most heartbreaking part of the series is how it consistently prevents its characters from finding happiness.
