Raionsuraisā

"There is no "good" or "bad" sword; a sword, as with any weapon, is determined in value by the hand that wields it. My blade is no exception. My blade has been at my side since my younger years. And it shall be at my side at my moment of death." - Momoko Kotone on Raionsuraisā.

Raionsuraisā (ライオンスライサー, lit. Japanese for "Lion Slicer") is the name of Momoko Kotone's sword. It is a fairly standard katana, bearing a slender and slightly curved blade. Raionsuraisā has a rectangular tsuba and it's hilt is wrapped in red dyed ray skin. Raionsuraisā is sheathed in a black scabbard.

Momoko refers to this blade as a Meitō (名刀, lit. meaning "Famous/Excellent Sword") due to her own forging it and it (alongside herself) achieving a reputation on the battlefield during the Fourth Shinobi World War. Raionsuraisā's status as a Meitō indicates a history and points to the sword having become a part of the fame and identity of it's wielder.

Momoko has shown great skill and expertise with the blade, wielding it seemingly effortlessly and using it to cut down a great number of enemies in the course of battle. The blade was instrumental in the defeat and sealing of Momoko's resurrected sensei, Isamu Eiji.
