The manga bleaching by Tite Kubo ended in 2016, but despite the conclusion, that universe lives on in some form with manga spin-off Burn the Witch. However, the fans remain mostly attached to the characters who shaped their generation like Ichigo Kurosaki, Rukia Kuchiki, and all the other Shinigami.
Between however, there are also some arrancars for more popular characterswho have favourited the Hollows who managed to evolve to a higher level and who were the main enemies of a very long story arc of Bleach. Among the arrancars, Nelliel Tu Odelschwank appears, although he is not an enemy of Ichigo. A former Espada deceived by Nnoitra and Szayelaporro, she becomes a child but survives to return to adult form during important battles.
She, too, will return in the new Bleach anime set during the Millennial War saga, and will receive some minor design updates for the occasion. The new Nelliel Tu Odelschwank was picked up by cosplayer Indra Rojas who decided to create a cosplay and post it on her Instagram page. You can see them in the post you can see below Cosplay by Nelliel Tu Odelschwank with the usual skull on his head but an outfit a little different from the one we saw during the Hueco Mundo arch in Bleach.
All that remains is to wait see it again in animated form, with the Bleach anime slated to restart in 2021.
