Faintly Arrives! is the third volume of the Katekyo Hitman Reborn! series.
An athletic festival starts in Namimori Middle School and Tsuna is forced by Reborn to enter. However, after several competitions, Tsuna's team loses and all the students end up fighting. Reborn also tests Tsuna by making him think he killed a thief, but the would-be victim turns out to be working for the Vongola. Later, Reborn starts a Mafia competition for his own birthday, which lands Tsuna, whose birthday was on the same day, in the hospital. One day, another infant assassin named I-Pin appears in order to kill Tsuna, only to discover that she mistook him for someone else, so she ends up living with Tsuna as well. When I-Pin later befriends Haru and Kyoko, she unknowingly gives them poisoned dumplings, however, they survive when Reborn shoots them with Dying Will Bullets.
