Amenokoshin

Amenokoshin (天甲信, Amenokoshin) is a unique Space–Time Ninjutsu used by Masayoshi after gaining his unique Tenseigan.

Usage
Using his Tenseigan, Masayoshi is able to create portals that allow him, others, or even objects such as jutsu to travel across certain distances. Masayoshi can open a portal anywhere he can see. Thanks his Tenseigan enhanced vision range, Masayoshi is able to see almost 20,000 km, making the range seem almost limitless in the midst of battle. He is only able to open one portal at a time, meaning one entrance, one exit, and after the technique is used five times it requires a cool down time. Similar to its parent technique, the movement is instantaneous, allowing the users to catch their opponents off guard.

Masayoshi does not only use this technique to teleport people, he can also use it defensively to protect himself or others from any damage. By creating a portal in front of himself, Masayoshi can send a technique heading towards him into the portal, and redirect. When forced to react quickly Masayoshi often creates the exit behind him, but when given enough time he may generate the exit behind his opponent. He also uses it to enhance the speed of his technique by throwing into the portal and having it exit right behind his opponent.

Using his Tenseigan ability to focus on chakra who've travelled to another dimension, Masayoshi is able to teleport to different dimensions, but it waste almost thirty percent of his chakra to do so.

Trivia

 * This technique seems to be unique to Masayoshi because of his relationship with Hamura Ōtsutsuki
 * Some consider this technique a downgraded version of Kaguya's Yomotsu Hirasaka.
