Kiichi and the Magic Books, Volume 4 — Taka Amano

After the death of his mother, Kiichi was ostracized from his village when it was revealed that he had a horn and pointed ears. Alone and with no clue as to his real identity, Kiichi encountered Mototaro, a traveling "Library Man" who possesses a magical book that may hold the answer to Kiichi's origin. How and why did Mototaro become a librarian? In flashback, it is revealed that he has reluctantly chosen his profession--only a personal tragedy keeps him returning to the Book Depositories and the Researchers. Back in the present, Kiichi is headed towards the next Depository and he's determined to go it alone. Hunted by several factions wanting to exploit him, Kiichi is afraid that he will bring more trouble down upon his traveling companions.
