Tenrō (天狼) is an elite team and a former genin team consists of two 3-man cells with a jōnin leader each. The structure of this team was specifically formed and proposed by Shikamaru Nara to create an elite team which will be trained accordingly and sent to various high rank missions thus will develop their abilities. These students later were split into two four-man subdiv-cells called Raijin and Fūjin. Unlike the normal 3-man cells, these teams were excluded to balance the genins abilities as it consists of high potential genins only.
