I was a NEET (Not in Education, Employment, or Training), but one day, when I went to the convenience store, I was killed by a robber. After that, I was suddenly chosen by a goddess who appeared out of nowhere and was reincarnated into another world. However, my reincarnated form was unexpectedly a ’plant’...! Moreover, for some reason, the monsters and humans I meet are calling me ’World Tree-sama’!?
