Chichi × Maruhi × Kokuhaku
Mito gives Gon a box from his father, Jin. Upon opening it, Gon and Killua find an encoded ring, a cassette tape and a ROM game. On the tape, Jin tells Gon not to find him. After the tape has played, it rewinds itself and erases the contents completely. Outside, unbeknownst to Gon, Jin flies overhead on the back of a monster perched on the back of an even greater monster.
