Natsume's Book of Friends

While out with Touko-san, Natsume spots a hurt youkai. Quickly he chases after it but as he goes to help it, it is eaten by a much bigger youkai. Natori and Hiiragi appear right after the youkai escapes and they invite Natsume to the Assembly of Conjurers. Here Natsume can not distinguish between human and youkai and is hopeful of finding people who understand him. Though this may be what Natsume has always wanted; he is too soft-heartened to realize everyone's intent. (Source: Wikipedia)
