Spiralling Ring

Menma creates a dark Rasengan-like orb of chakra surrounded by a series of white rings of chakra that orbit the main sphere. These rings then align into one disc-like shape around the orb, causing the rings to resemble planetary rings. It matches Naruto's Wind Release: Rasenshuriken in Sage Mode in power.

Trivia

 * The technique's name is a pun, similar to certain techniques of Kumogakure ninja, in which it has an English name with a given kanji that somewhat match the pronunciation. In this case, "輪虞" is pronounced as the English word "ring", but literally means "fear wheel".
 * The proper spelling of the technique's name was first revealed in Naruto: Shinobi Masters, a Japanese social game available for iOS and Android phones on the GREE mobile social gaming platform.
