From my test run, Summer Musashi is not that reliant to Tamamo / Nero / Para.

She can race just fine with her second skill; first skill is decent, third skill is universal boost that even rag-tag team can capitalize and you can treat it as "turn end" feature by purposefully made her weak; simply remove her after you done wave clearing + some damage to boss.

So her drawback is down to low NP damage. However that's something happened to every AOE Arts in this game thanks to their spammability; what remain became problem of high damage access from start that standard of current Berserker if you not have survivability to sell like Cu Alter or Herc-- and its still acceptable thanks to critical damage boost on her first skill;

Combined with her second and third you can expect good start from budget setup. She could be better if she have NP Charge but we know it won't happen given benefit of her second skill Lv. 10 is absurd enough for an Arts Berserker.

That differentiate her enough from Vlad, who have little to contribute if you not giving efforts to his survival, and Hijikata, who hardly contribute unless you can hit certain amount of damage before leaving.
