Nekoyashiki Haru, a 17-year-old male, dropped out of school to play in a band. He's blind, drinks a little but never smokes. He loves to draw, though he's not very good at it. After many years, he returned to Shimokitazawa, only to find he'd completely lost his sight. Fortunately, a miraculous pink soft-bodied creature led him to safety, saving him from a treacherous staircase. From then on, he began his life as a staff member at the livehouse called "Starry Sky." ……………When he went to sleep… he kept hearing someone whispering strange things in his ear. Yellow: No need to try anymore, kitty. I'll always be by your side. Blue: Let's just be friends. I can't live without you. Red: I'll snatch you from you, please wait a little longer. Pink: Thank you… Thank you for watching over me. I'll repay you with my whole life… But if you don't accept, I'll go to $^^•$+" (an incomprehensible voice). "What will my ending be like…?" Nekoyashiki Haru couldn't help but wonder, realizing he wasn't the only one in his family.

(Currently implemented: Lonely Rock, Bangdream! It's My Go!!!!!) The idolization trend is sweeping the archipelago, and the light novel industry is no exception. At the behest of a school library, high school author Togawa Akie picks up her long-forgotten electronic keyboard skills, aiming to boost sales of her new work by forming a band. To achieve a more "original" commercial effect, the library doesn't assign her a permanent bandmate. Forced to leave the classroom and scour the streets for collaborators, Togawa encounters a group of girls who, under the name "End," are pursuing their dreams in a band. By chance, she and a girl named Chihaya Aine become entangled in Nagasaki Motoyo's scheme, ostensibly to form a band. "Perhaps everything originates from a fabrication woven from profit." "Then what is the meaning of these emotions and bonds born from this false heart?" (Tachibana, a fusion manga set in the world of idols and bands.)

"Are you my knight?" the silver-haired boy asked, smiling at the blonde girl before him. This was their meeting when they were ten years old.

"Are you my bride?" Gently embracing the blonde girl, his companion for ten years, the boy questioned yet affirmed. This was the story of eighteen.

"Are you my king?" Half-kneeling at the throne, he looked up and smiled at the girl holding the Sword of Victory. The boy's smile was the same as the boy's ten years ago.

"I can be without eyes, but you, and all of Camelot, cannot be without eyes." With a smile, he forever gave his eyes to the girl, who had lost them due to the red dragon's curse. The boy had no regrets. This was twenty-five years of happiness.

"So, Arthur? Pen? Dragon? Artoria, King of Knights, young lady, will you... walk with me for life?" Smiling, he extended his hand to the girl, and the silver-haired boy asked the same question two thousand five hundred years later. This was a bond that had lasted two thousand five hundred years.
