Other name: 夏にはため息をつく, 夏目友人帳, 妖怪联络簿, 나츠메 우인장, Le Pacte des yôkai (French), Natsume Yujin-Cho, Natsume Yujincho, Natsume Yuujin-chou, Natsume's Book of Friends, The Natsume Book of Friends
Summary: From Storm in Heaven: Natsume's just an ordinary kid, except he can see spirits, just like his grandma Reiko could. Reiko, though, used to bully the spirits, and bound them to her will in the "Book of Friends". Now that Natsume has inherited this book, a never-ending stream of spirits is coming after him. With the help of a spirit "cat" (who really just wants Natsume to die so he can have the book), Natsume spends his days dissolving the contracts that bind the spirits and trying not to get killed. Extras: • Manabiya no Sumi (The Corner of the Schoolhouse) in v.6. • Natsu ni wa Tameiki (w)o Tsuku (A Midsummer Sigh) in v.7.
