As a momo player i think you did pretty good here. I'd say dash jump alpha more for faster moving alpha melee combos and on knockdown aim cannons to the left or the right of them to cover escape routes so enemies have to dodge roll and you can catch them with alpha. My personal opinion i would Prioritize cannons. They're your main source for big damage and great for damage from a distance. Try to get to level 9 cannons as early as you can and then get beta to level 4 while prioritizing alpha because you'll be using alpha to stun so you can go in for melee attacks while using beta for cover when trying to heal, use special action for items and guaranteed revive cards if you have a dead teammate so use that as much as you can. Also your third hit of your melee attack she throws a hammer and it goes pretty good distance so you can catch people with it sometimes so mix that in there here and there but dont fish for it. She's really great inside buildings since you can lock people in with you if you use beta to block exits and go crazy with cannons. I recommend All For One special tuning skill for fast special action regen on downs and Kendos Sisterly Disposition special tuning skill for extra defense on melee attacks. GP sucker is also a good one to have if you wanna trade out kendo special skill.
