One Piece Chapter 1021: “Demonio”.

Most part of the chapter is Robin Vs. Black Maria battle.

Robin has a little flashback with Sabo, Koala and Hack.
– Koala wanted to teach Robin the “Fishman Karate”, while Sabo wanted to teach her to use the “Ryuusouken” (Dragon Claw Fist).
– Robin learned Hand-Based Martial Art from Sabo. When the crew was going to the fishman island, they were intercepted by a rock.. Robin applied what she had learned from the training of the Revolutionary Army and smashed the rock with the Higantescu Mano technique (the same one with which she hit Black Maria with her palm in the face).

Robin uses a new technique called “Demonio Fleur” (Demonio means Devil) transforming her giant body into a black demon.

All Black Maria techniques end with “Maria”.

At the end of the chapter:

– Luffy is eating and seems recovered.
– Momonosuke asks Shinobu to use her “Juku Juku no Jutsu” to turn him into an adult.
– Shinobu tells Momonosuke that she cannot accept his request to make him become an adult.

Break next week because Weekly Shonen Jump won’t be published (holiday week).
