[Well, if it works, it works. Mikumo's seen some questionable weapon decisions made in her time, so rather than question using a bow as a melee weapon, she gets the spray done before the drones recover from the sudden formation break brought on by Hajime going melee on them.
However, one of the bots he's not currently bludgeoning seems to pick up on the magic from the spray, and starts aiming a missile down towards Mikumo - given that, she heads back up towards the cluster of them, opening her canteen of water and drawing it out with her powers, then sending a shower of arrow-like water constructs up into the underside of the bot, worming through cracks in its armour to damp its electronics and short-circuit it.]
and apologies in return, i went on a semi-hiatus
