Stand My Heroes: Piece of Truth - Season 1

Rei Izumi is a rookie regulatory official with the Drug Control Department, who has just been appointed as a scout to gather members for a new investigative agency called STAND that specializes in unsolved drug-related cases.

Rei tries to recruit members of Revel into STAND and is met with varying attitudes. Hatori seems rather fond of her, but the others seem to have some reservations.

The police and narcs confiscate a new drug. Rei attempts to recruit novelist Makoto Tsuduki into STAND but receives a cold reception. Meanwhile, Makoto's younger brother and actor, Kyosuke, seems much nicer to Rei.

Kyosuke takes Rei out on a few dates and the DCD continues their investigation on the new drug they confiscated. Meanwhile, Makoto gets taken in by the police for questioning regarding an old case which causes trouble for both Tsuduki brothers.

After having her scout duties put on hold, Aoyama asks Rei to help him with an investigation he'd been working on during his free time.

The DCD end up helping out at an event put together by the Ministry of Health, Labour, and Welfare, the MPD, and the fire department. Meanwhile, Rei and Aoyama try to find out who sent Rei the threatening message.

Rei and Aoyama go to meet with Soma Kujo, but things don't go that well. Rei is determined to not give up and visits him on another day. On her way there, she encounters Kirishima fighting a deer.

Miyase helps Rei dig further into the case to see if Kujo is really connected or not. Meanwhile, Arakida has some second thoughts about Izumi being completely useless.

Hattori tells Rei about something that happened in his past that ties in with the Anonymous Case and in return, he wants her to try to get Makoto to talk.

Rei goes to visit Sara and Kyosuke. Kyosuke trusts her enough to ask her to save his brother, and manages to convince Makoto to meet with her. Makoto then tells her his connection with Ida, and...

Rei, the DCD, and STAND all confront Kujo at the site of a supposed drug deal, but something seems off. They take him in for questioning and the more they talk to him, the more it seems that he was framed.

The one who framed Soma Kujo is revealed and Rei's life is in danger. Will Rei and STAND be able to stop the true mastermind behind all of this?
