Zassou Tensei: Elf no Sato de Taisetsu ni Sodateraretemasu

One day, I woke up in the middle of a field of grass. How could I have been reincarnated as a weed? First thing, I recovered my energy through "photosynthesis." Then as I was testing out my skills, such as "Energy Drain," which allowed me to absorb life force from other creatures, and "Seed Generation," which let me freely produce fruits and grains, I ran into a young elf girl! She took me to the high-elf village where she lived... This is the story of a young high elf and a weed, a plant reincarnation fantasy with a unique duo.
