Sorry, but the shirt Uke ist wearing in chapter 23 shows LITERALLY a nazi swastika (Hakenkreuz). ( T﹏T )

And I agree with you. I know where it's originally from but for me it (sadly) connects to that part of history.
It's as much a buddhistic symbol as a Nazi symbol. That was the first thing on my mind.
And I know the author didn't use it like that and they themself probably think of the buddhistic symbol first.
It's just two different perspectives caused by different upbringings.
Don't split them up ╥ o ╥
