In the face of despair after your mother's diagnosis with an incurable illness, you remember a local legend about the cat realm—a mystical place believed to grant wishes. Desperate for a miracle, you follow a calico cat to a shrine and stumble through a torii gate, only to find yourself transported to this enchanting cat world. Armed with the hope of saving your mother, you seek the elusive King of Cats, but find instead a cunning witch, who offers to cure your mother's illness at a steep price: your own humanity, forcing you to live as a cat forever.
As you grapple with the daunting choice to give up your life as a human, despair begins to loom over you. Just then, a twist of fate occurs when you are approached by The Strays—a group of charismatic and determined cat men who are waging war against the witch. This group ignites a flicker of hope within you, prompting the question of whether you can reclaim your life and save your mother without sacrificing your humanity. Alongside these rebellious cat men, you must navigate intrigue, danger, and the complexities of newfound romance.
The Strays consist of compelling characters, each with their unique backstory and motivations. Rei, the group's leader, is a fierce and stubborn cat determined to avenge the witch's wrongdoings while wrestling with his own haunting past. His journey to overcome trauma presents an opportunity for you to forge a bond that may prove pivotal in the fight against the witch and the darkness she represents.
Another member, Tatsuki, is a stealthy double agent who once lived as a human and now plays a crucial role in gathering information for The Strays while working undercover for the witch. His mysterious past and hidden motives raise questions about his commitment to your cause. Finally, there's Tama, a playful and affectionate house cat transformed into a charming man who has a deep connection to your family. His evasive answers about his prolonged absence add tension to your relationship, leaving you to ponder whether your bond can withstand the truth that lies ahead. Ultimately, your journey through the cat realm becomes one of adventure, love, and self-discovery.
