Alright, so i'm gonna be the first one to review this short manga. As the title "Dungeon Hoiku" says the manga is about a man named Takashi Koizumi who dies in a very pathetic way and gets reincarnated into a fantasy world. There he tries to conquer dungeon b summoning an OP deity but only gets a goblin, a very weak chibi goblin and a harpy with no other option left he teaches them or basically he just babysits them. The art and story is okay, not too good but also not too bad. I only read this because i found it somewhat cute.
