Yuu Tanaka 
A Late-Start Tamer’s Laid-Back Life (Manga): Volume 4 [EPUB ebook] 

While chopping down trees in a forest, Yuto and his new friends Ashihana and Sawyer are caught off guard when they suddenly find themselves in the middle of a boss battle! That’s right—it’s time for Yuto’s first boss encounter, as the team faces down a curious foe known as the Shrub Worm. Then, once the dust has settled, it’s time for Yuto to pay another visit to the Sequoia Dryad—this time with the Quick-Eared Cats in tow—to shed some light on the mysteries of the Dryad’s blessings.
