already gone into defense mode, they only went into attack when Keitaro got attacked and by then that's starting the fight 1 man down
Ngl tho I know its kinda assholish but I'm surprised they don't use Keitaro as bait for the ghosts since ghosts tend to love him

while they attack the ghosts from a safe spot
Also I just realized that while this isn't 100% the first ghost that tackles the soul, Its kinda interesting that they don't have something to protect it yet, like they have that charm back home that has ghosts in it so when they take life sustaining injuries then those charms take the hit instead BUT they don't have anything to protect them when soul dmg plays into effect which is kinda wild ngl
