In this volume, Kawaki is the main plot focus from his fight from the guy from Kara to his fights with Boruto.
Kawaki fights off a guy called Gorou, who wants to take him back to Jigen, who seems to be the leader of kara. It is during this fight that the abilites of Kawaki are on display. His two main assets are his Karma mark which absorbes attacks, and his mechanical modification. Which Katesuke described as being celluar modifications. To me this sounds like nanotechnology. With these mechaical modications he can harden and soften his body. It's like he has Kimimaro's bone weapons and Mitsuki's screchy limbs. Thought he only showed the hardening abilities during the fight. Which implies he has more abilites yet to be shown.
After the fight with Gorou was over, Naruto took Kawaki home to stay with him. Naruto said it was to gain his trust. As he thought confiding him in a cell would only make him more warry. While it might sound like a good plan on paper it does seem to place Hinata and Himawari in alot of danger, the whole village as well. From both Kawaki and the members of Kara who want to retrive him.
After the serious fight is over Kawaki has many small conflicts with Boruto. They are trying to parrel the relationship Naruto had with sasuke using Kawaki. It think the sasuke dynamic is plenty filled by both Sarada and Mitsuki. Sarada has the Name calling and Rival part. Where Mitsuki has more the be the sun to my moon dynamtic. Which are the more pleasent and nostalgics parts of Naruto and Sasuke's relationship. The only part for Kawaki to fill would be the homicidle compounent of sasuke during the shipppuden era. Which would not work with Kawaki since Boruto is not that attacked to him. To me Kawaki remineds me more of Gaara. The relationship that could develp between Boruto and Kawaki should be more like the Naruto Gaara friendship. They meet when they where 12 and karma are reminicent of the power and trama of being a jinchuriki.
It was nice to see Hinata and Himawari in the manga althought thier appearnce was limited. This might be the one area I prefer the anime over the manga, the amont of time we get to see Hinata and Himawari.
Overall decent volume, I liked that action in the begining. The only thing I did not really like was that this story is trying to force the Sasuke and Naruto parrel between Boruto and Kawaki. When Kawaki really remineds me more of Gaara.
