Reborn! Vol. 07: Hot Summer Arrives!

Tsuna is targeted for assassination, so a weapons tuner for the Vongola Family arrives to upgrade Reborn's arsenal. This winds up creating a fair amount of chaos, but it's summer and Tsuna soon finds other distractions--learning to swim, taking part in a summer poetry contest, racing into the ocean to rescue a girl in distress, and defying a ghost bent on taking him to the "other side"!
