Mitsuki had so much potential as a character.... but they decided to make him just a Boruto spectator #1 personal fanboy. smh
Oh well, I guess it can't be helped. You're useless and you will never shine in this series unless your name is Boruto.
Chapter.Twenty-three.
Half of those were recaps.
This is the equivalent to the land of waves arc with the difference being the story(arc) is centered on Boruto/Kara/Kawaki/Ao/Seal. This is to set up for a bigger plot.
Sarada's growth and development along with Mitsuki's will come. There's not room for them because they havent laid the foundation for the main plot. Look at Hero Academia. Multiple characters with well rounded development.
Prior to that, the focus outside of gags was Deku's development and his role as All-Might and the villains after him. Later on we see several of the cast's quirks(figuratively and literally) and interests fleshing them out.
Why is everyone on this forum acting as if Boruto has 100+ chapters. Mitsuki's mission is to watch and observe Boruto's growth, finding his own identity while also being his friend. That dude has been his Day one friend since the start of the series, he's not his personal fanboy, they have disagreements and different views. As I recall, he was trying to snuff Sumire completely.
If you want a series like that watch/read Soul Eater, Eyeshield 21, My Hero Academia or something. If you're that impatient.
Or watch the anime like a sane person.
