Grand Bleu

Appearing in the JORGE JOESTAR light novel, Grand Bleu belongs to Muryotaisu Nijimura, a character hailing from the 37th Universe. It is not one entity but a colony of three sentient dolphins, each sporting its own markings, sharp teeth and streaks trailing back from the eyes. Because they possess minds of their own, the dolphins carry individual names, and their master began with a single one before two more took form.

The dolphins fly through open air at blistering speed, likened by Joji to rockets tearing away into the distance. As Stands, they bend the usual rules of motion: a passenger riding one feels no wind and no pull from spin or gravity, because the creatures disregard inertia entirely. Muryotaisu can grant other people permission to ride, and the dolphins heed a rider's commands so long as that rider stays obedient to Muryotaisu himself. Each dolphin seats up to two, and their reach is vast, letting them soar far from their summoner with passengers aboard.

Muryotaisu Nijimura is the only wielder of Grand Bleu. He names his three dolphins Yohana, Enzo and Jacques, drawing the titles from characters in the film The Big Blue, the same movie that lends the Stand its name.
