Daikokuten

Daikokuten is a dōjutsu of Isshiki Ōtsutsuki's unspecified dōjutsu. Through its use, anything he has previously shrunken using Sukunahikona can be instantaneously retrieved and enlarged at the focus of his gaze. The objects retrieved are stored within a dimension where time doesn't flow, allowing them to maintain a pristine condition. Objects are enlarge with such speed that they can catch attentive opponents such as Koji Kashin off guard while inflicting serious bodily harm.
