Nagareboshi

Nagareboshi (流れ星; Literally meaning "Shooting Star") is a large golden spear, passed on to every ninja in the Hamasaki clan, with the clan's Kekkei Genkai. It is described as "the barrier of heavens" and even earned the title of "Celestina" (セレス, Seresu), further adding to its reputation.

History
When Asuna Hamasaki was born, her grandmother knew that she was the next heiress of Nagareboshi. As she grew older, Asuna learned how to handle the spear and how to use it to protect the sealed spirit. During an invasion in her village, which is led by her brother, Aren Hamasaki, her mother ordered her to protect the seal before its too late. She came to the temple where the sealed spirit is found, but her brother took it away. She and her brother started fighting for the sealed spirit, causing the seal to break. Now, with the spirit released, it is now bound to Nagareboshi. Asuna used its blinding light to scare away the invading group, along with her brother.

Appearance
Nagareboshi is an all-silver spear with gold and orange trimmings. The spear's tip is very detailed along with the blade at the top. The blade bears a red cross and below the blade is a small golden axe. When infused with chakra, the spear glows with light twirling around it and small orbs which is used as a substitute for chakra.
