Multiple buddies
The protagonist Wilhelm and Topherf. Tei and Margaret. Licht and Schatten. The relationships between each character, whether friend or foe, are fascinating!



Well-developed world setting
A professional scenario writer and illustrator have teamed up to create a indie game filled with things they want to do that cannot be done commercially.

The Case of the Impersonation of the Duke's daughter of Dirk.
An incident related to the search for a queen for Leonhard, King of the Phoenix Kingdom. It started when a person related to the king who came into contact with one of the queen candidates, Duchess Margarete, was in a brainwashed state. The truth is that Duke Dirck and others, who had lost Margarete, plotted to seize control of the state by using an imposter of Margarete and hallucinogenic drugs. The case was supposed to have been solved...

The Corpse Killer.
One of the urban legends in the Kingdom of the Phoenix. It is believed that he is the guardian of death to prevent it from being misused. There is a "Corpse Killer" in the Phoenix Kingdom. Before he is reborn and becomes a phoenix, a black-robed messenger comes to see if he has committed a crime. If he is guilty, he kills again."

The Phoenix Tribe
A long-lived tribe of immortals. They burn to ashes once every 500 years, but are reborn from the ashes and live forever. The blood of the phoenix tribe contains a lot of magical power and has a flavor similar to that of fine wine. They are born with immortality and become immortal when their magical power reaches its peak. However, their mentality is no different from that of the short-lived species. Unable to overcome the fear of death (pain and loss) that the short-lived species have, many of them refuse to come back to life and choose a long sleep. They take the form of humans, but can also take the form of birds.

Character


The protagonist Wilhelm
The protagonist. He is a new knight of the Kingsguard. He is a prodigy in martial arts and can use a wide variety of weapons like a role model. In order to assist his father, a weapons craftsman, he has been experimenting with prototypes. Because of his keen senses, he is often surprised and frightened. He has a strong will, but he is not averse to trouble and is always willing to go along with others. Since he was just recruited to become a knight, he is looking for his own goals.
Secret: He is known as the "Corpse Killer" because he once test-killed a corpse. For that reason, he doesn't want Tofaf to hate him.


Alchemist Topherf
TS heroine. Genius alchemist. She has longevity because she creates her body by alchemy and transfers her soul by magic. She loves fashion and changes her appearance and gender according to her mood. As a person who deals with souls, he judges others by their souls (character and personality). He is cheerful, friendly, and popular.
Secret: He is afraid of being hated, so he hides his "natural appearance". He is indebted to Wilhelm.
