But it says "shinbu fusatsu"...
Indeed it does, but googling "shinbu" gives nothing relevant while "jinmu" could lead at least to the MAL page.
I've found that through "kikiyu takase".
Seems like a poorly known novel which haven't even been translated properly.
Should we wait for our Japanese users to search on the other side of the moon?
