10 nen goshi no HikiNiito o Yamete Gaishutsushitara Jitaku goto Isekai ni Ten’ishiteta [WN]
When I was going out from my house to stop become a Hiki-NEET after 10 years I was transported to another world
For those who (like me) wondering why Yuuji from the cover so much different from the WN, here is a short explanation taken from the post of Okashira from the forum Animesuki: "In the LN, he is of high school age, and he also gets transported along his female cousin Yoko. who visits him daily to cook and check on him, and they do seem to have a somewhat normal family relationship."
