A private detective and the returning protagonist from The Shell Part I: Inferno. Reiji is both lazy and sloppy in his personal life but has a strong sense of duty in his work.

After losing his fiancée while working a case, he quit the police force in order to wrestle with his past alone as a PI.

These days, he lives with his sister Yukari. He continues to search for a girl who was kidnapped after getting involved in his investigation of the Girl in Shell case.

Another protagonist, a jobless man whom Yukari Tokisaka prevented from ending his life in Inokashira Park. After leaving the hospital, he’s been temporarily employed as an assistant at the Tokisaka Detective Agency.

He has currently lost some of the use of his left hand due to the method by which he attempted suicide.

A newly transferred member of Yukari’s class at Oba Girls’ Academy. She seems to tend to avoid other people because she’s quiet and a little awkward.

This has left her isolated, but Yukari and her friends’ warm welcome is beginning to melt the ice of her heart.

Reiji Tokisaka’s perfect little sister. Flexible and tolerant without being a pushover, she’s the quintessential Japanese woman and always happy to look out for her brother. Her one flaw is a disturbing fondness for insects that even her friends have to fear.

She’s moved up a year since The Shell Part I, but still remains a proud member of the Art Club.

The personable and supportive owner of the Moon World café.

A childhood friend of Reiji’s, and nowadays more than just a friend.

An odd girl with a mysterious energy.

Everything she says and does can only be described as eccentric; the way she talks to the stuffed rabbit she carries around can be misleading, because she’s actually remarkably intelligent.

A kimono-clad girl who arrived in Hitogata shortly before the festival as a "guest" associated with the Shigusa family.

Typically silent and always mysterious, she also gives off the impression of being somehow fragile and breakable.

The younger twin sister of Ayato Hinagami, whom she loves for his quiet kindness.

Karen is fascinated with style and fashion.

A childhood friend of Ayato and Naori’s, and the same age as the Hinagami twins. Able to make friends wherever she goes, she sets the mood among the group.

It seems she also harbors some special affection for Ayato, and she often gets excited over fashion magazines with Karen.

The next proprietress of the Futami Inn, the only hotel in Hitogata. As her parents are both deceased, she was raised by its current proprietress, her grandmother Yoshie. Perhaps that is what has made her so dutiful, serious, and difficult to please.

Her work assisting at the inn may also be what has made her the most mature of her friend group.
