Voice: Kōki Uchiyama

When that happens, you'll be the only one who can protect everyone." He blindly believed her words, and has spent the majority of his life preparing for that moment. None of his other friends believe him though he has become a social outcast. However, he refuses to change his beliefs, and won't listen to what anyone else says.

Voice: Mikako Komatsu

A descendant of humanity from the far future, which has been destroyed by a pandemic. She is one of the few humans who was resistant to the revisions. Milo is also an agent called a "Balancer" who works for the organization AHRV, which protects the future where humanity still survives. She has strong feelings of hatred toward the revisions for their massacres of AHRV's members, and devotes herself to the organization entirely. Emotionally inexpressive, she lives a to-the-books, orderly life.

Voice: Nobunaga Shimazaki

A 17-year-old, second-year student at Seisho Academy and Lu's twin brother. He is an excellent student, and athletic as well. He dislikes Daisuke for the childish way he's acting now that his dream of being a hero is coming true. But in fact, just like Daisuke, he remembers the prophecy Milo gave him: "Doubt everything." He has the capability to be a cool and collected leader, a talent he puts to good use in the S.D.S. (Shibuya Defense Service).

Voice: Rie Takahashi

Gai's 17-year-old twin sister. Just like her brother, she's good at sports and gets excellent grades. Strong on the outside, inside she is dependent on her brother, and follows him everywhere. Just like her brother, she is aggravated by Daisuke's overprotective nature, and keeps her distance from him. The only member of the team who doesn't remember Milo's prophecy.

Voice: Manaka Iwami

A 17-year-old, second-year student at Seisho Academy who is Daisuke's classmate. She goes by the nickname "Marimari". Easygoing and cheerful, she's beloved by her classmates, but she is also indecisive and lacking in confidence. Milo's prophecy to her -- "In the end, you'll need to decide for yourself" -- weighs on her heavily. She's been in love with Daisuke since childhood, but in the future world she has complicated feelings about the way he behaves as a "hero".

Voice: Sōma Saitō

A 17-year-old second-year student at Seisho Academy. Daisuke's one real friend, and the only person who understands him. He acts as a buffer between Daisuke—who tends to act on his own--and the S.D.S. He's always chipper and upbeat, but at the same time self-effacingly says that he "has no luck." He clearly remembers Milo's words to him from the kidnapping incident -- "Accept everything" -- and for this reason, it kind of seems like he's given up.

Voice: Yukari Tamura
