It's an Alice in the country of hearts fanfic. Akumi Chi is Alice's ex-boyfriends little brother. He always carries a sword his father gave him. He never let's it leave his sight, it always attached to his belt. He visits Alice often and always says how sorry he is about his brother. Akumi comes over even if Alice isn't there. Alice said it was fine, he usually goes over and takes a nap in their garden in the backyard. He usually brings his favorite book 'Demon Blood' with him to the garden. He was named after it. He has read about a million times. While sitting on a tree branch and reading his book. A rabbit that looks like a human grabs him and drags him down a whole.
