Comprehensive Comics: Blue Glow

This world is made of jet black and blood red Ghoul monsters are everywhere, and space earthquakes occur frequently. There are alien spaceships flying around in the sky, and gastrea animals destroying the city underground. It is common for the Holy Grail War to destroy a city, and ANBU wars between superpowers are not uncommon. I would like to ask, in such a hopeless world, as an ordinary person, how should I survive? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
