Toiletta

is a Rank C Drain-attribute Yo-kai of the Eerie tribe.

The Yo-kai Medallium bio reads; "Having settled in the school, she's always looking for someone to play with. But she's usually so shy, she can't bring herself to approach others. Her favourite place is the girls' bathroom."

Hanako-san evolves into Foiletta when fused with a Cursed Diary.

Appearance
Hanako-san appears to be a little, pale-skinned girl with large black eyes shadowed by her short, dark grey bob-cut. She wears a white top with a cherry-red skirt with suspender straps and matching loafers. Her socks are white. As a Yo-kai producer, she additionally wears pink glasses.

Personality
After deciding to turn from a silent, stone-faced bathroom legend to a Yo-kai producer, she develops a more confident personality, shown in her attempts to get Snartle fashionable after he is almost arrested for wielding swords in public. In a later episode, she appears in Nate's room to help Grumples regain her youthfulness, which changes her to Everfore. Despite Hanako-san's best attempts, the effects were temporary. She also appears in Inaho's story when she dressed Suspicioni, Dimmy, Negatibuzz, and eventually Drizzelda causing them to lose their souls. After she is confronted, she takes off the clothes which revives the Yo-kai.

Nate and Whisper
Despite only being summoned by Nate twice since he received her medal, Hanako-san is always willing to help him with a problem, usually by using one of her designer skin creams or her knowledge of fashion.

Abilities and Powers
Hanako-san is one of the few Yo-kai in the anime that allow humans to see them without a Yo-kai Watch. When a child spins around in place three times or calls out "Let's play together!," she'll appear to them. This usually leads to the child running away in terror.

How to befriend
Hanako-san appears in the Springdale Elementary bathroom stalls during a request.

After helping her scare his classmates in new ways, Nate is finally terrified by the Yo-kai himself after receiving a mysterious DVD in the mail with Hanako-san hidden inside.

Afterwards, Hanako-san decides that she wants to help others improve themselves, and becomes a "producer" for other Yo-kai, training them in fashion and appeal.

Origin
Hanako-san is based on the urban legend of Toire no Hanako-san (トイレの花子さん, "Hanako-san in the toilet"); it dates as far back as the '50s and is one of the most popular and widespread urban legends in Japan, comparably to Bloody Mary in the USA. Incidentally, "Hanako" was a very common female name at that time, similarly to the English "Mary".

She is said to be the ghost of a little girl who haunts school bathrooms, and if someone walks to the third stall of the girls' bathroom on the third floor, asks "Are you in there, Hanako-san?" and knocks three times, she will answer "I'm here". The story of her origins and accounts varies greatly from place to place, but she is generally imagined as a grade-school age girl with a bob haircut, a white shirt and a red skirt with overalls. Depending on the source, Hanako-san can be friendly, mischievous, or actually a monstrous entity posing as a little girl, who will promptly seize those who call its name.
