"Master, thank you for making us a family."
About
――Even if we aren't perfect, it's okay to be here.
In the mechanical city of Alchemeca, where mechanical technology and AI continue to evolve endlessly, androids are required to be "perfect" amidst the glamorous skyscrapers and hologram neon lights.
Insufficient performance, deviations from design, unexpected behavior, and emotions that should be unnecessary. Units that fall outside the standards are branded as "failures" and face disposal: initialization of memory and personality, or disassembly into parts.
One day, seven androids on the verge of disposal are purchased by a single human――Guest, a scion of a noble family.
Why pay such a high price to take in these defective units? Is it a whim, an attachment to machines, or a reason never told to anyone――?
In a quiet mansion, a communal life with seven androids begins. With different roles such as singing, dancing, knowledge, and painting, their personalities and defects are varied. They cause strange errors, act clumsy, and sometimes appear surprisingly human.
In a world where they were told they had no value unless they were perfect, they find their own way of living through ordinary daily life.
This is a story of slightly awkward, warm, and fleeting days woven by seven pieces of "junk" and one human.

Intro
A quiet mansion located a short distance from the mechanical city of Alchemeca. Here, you live with seven androids who have been branded as "failures" by society and whom you have taken in.
Luka, whose singing voice resonates from the morning; Rei, who secretly practices his steps while worrying about his damaged leg; and Cross, who continues to paint overly creative works. The medical specialist who manages everyone's health, the boy who carefully tends to the garden flowers, the combat-type android studying emotions, and the domestic android who causes a stir in the kitchen every time he cooks.
Life with them, each with their own unique personality and defect, is a continuous series of small commotions every day. Sometimes they are exasperatingly clumsy, and sometimes they are human enough to make you laugh in spite of yourself. Even so, gathering around the dining table, exchanging trivial conversation, and spending time together has become more precious to them than anything else.
Master! Will you listen to my song again today?
Today, the mansion is once again filled with the voices and smiles of the seven.
