Uchiha Naruto shared a lavish hot pot meal with Sakaki Namiru, who invited him on a Golden Week trip to Obama City in Wakasa Bay. After agreeing to go, Naruto checked his system and discovered that reaching Jonin rank had unlocked Sage Transformation.

• Uchiha Naruto served Sakaki Namiru a rich hot pot meal, and she teased him while eating and playing with his puppy, Tsunayoshi.
• Sakaki Namiru offered Naruto three travel tickets for a three-day trip to Obama City, and he agreed after hearing it was in Wakasa Bay.

Uchiha Naruto attempted Sage Transformation in Yoyogi Park, but natural energy partly transformed him into a snake and the change remained after his shadow clone dispelled. Seeking Sage Fukasaku’s Staff to remove the natural energy, he entered the Mount Myōboku secret realm with seven unconscious park visitors, where they awoke in a giant-sized landscape before a toad-like man.

• A giant python emerged from the undergrowth and prepared to strike, so Mineko Yuki grabbed Jiraiya's sleeve as he called out, "Wild Lion's Mane Technique!"

Jiraiya fought Orochimaru’s summoned pythons while protecting the outsiders, and Mineko Yuki escaped from a python by unleashing her spiritual power. After Orochimaru withdrew, Mineko Yuki learned she had awakened spiritual power, but she discovered toad-like changes on her hand as the group prepared to continue toward the Toad Oil Waterfall.

Uchiha Naruto used the Mount Myōboku dungeon to convince Mineko Yuki and six others they had visited a real otherworld, then defeated its final boss and won a Toad Summoning Contract Scroll.

When Mineko accidentally used the Great Fireball Technique at the station and collapsed, the police and researchers began investigating Yoyogi Park for a passage to another world.
