🖤 25-ji, Nightcord de. — It starts here, and gets worst

• Mafuyu: Her emptiness deepens. She stops pretending, stops reacting, becomes completely hollow. She doesn’t just hide her feelings — she loses them entirely. She starts pushing everyone away, says “saving people is meaningless”, and even stops coming to meetings. Her Sekai goes totally black, nothing left at all. ​
• Kanade: She tries harder and harder, writes darker, sadder songs, sleeps less, gets sick, but nothing reaches Mafuyu. She starts blaming herself fully, thinks “I failed to save anyone”. Her belief in music shatters; the piano in her Sekai starts cracking. ​
• Ena: Her dad gets even harsher, her art gets ignored, her online likes drop. She panics, gets bitter, starts snapping at everyone: “You all have it easier than me!” She stops writing lyrics, says “If I’m not praised, I don’t exist — and nobody cares anyway”. She and Akito stop talking completely. ​
• Mizuki: The pressure to hide their secret becomes unbearable. They feel more and more alone, scared even Nightcord will judge them. They start skipping meetings, say “I told you it’s okay to run away… so I’m running away first”. Their Wonderland Sekai fades to gray, ribbons and lights disappearing. ​
• End state: The group barely talks, only meets out of habit. Songs turn cold, lifeless. The Empty Sekai starts leaking dark fog that spreads to all other Sekais.

🎸 Leo/need — Old wounds reopen and never heal

• Ichika feels she’s failing everyone, that she’s “only good at following others”. She stops writing songs, says “I can’t lead you”. ​
• Saki’s health gets worse; she has to stay home longer, starts thinking she’s just a burden. She hides pain, acts happy, but cries alone. ​
• Honami thinks she’s only useful when she’s helping — when she can’t fix things, she withdraws, feels “I don’t belong anywhere”. ​
• Shiho gets distant, thinks “We only stayed together out of pity”. She wants to leave music entirely. ​
• Result: The band falls silent. School Sekai turns cold, sunset gone, windows boarded up, instruments gathering dust. The promise they made is broken.

🎤 MORE MORE JUMP! — Dreams turn to ash

• Minori works harder than ever, but fails every audition. She starts believing “I’m just not talented enough — I was delusional”. She quits trying. ​
• Haruka’s past mistakes catch up; people start hating her again. She thinks “I ruined everything for everyone”, stops smiling. ​
• Airi gets ignored, her confidence crumbles: “I was only ever popular for my looks, not my heart”. ​
• Shizuku realizes no one sees her, only the “perfect idol”. She feels completely lonely. ​
• Result: They disband. The bright Stage Sekai goes dark, lights cut, curtains closed. They stop wanting to be idols at all.

🎧 Vivid BAD SQUAD — Rivalry turns into hate

• Akito pushes himself to breaking point, gets injured, refuses to rest. He hates himself, hates his dad, hates Ena, hates that he’s “not good enough”. He starts saying “I’ll beat everyone… even if I destroy myself doing it”. ​
• Kohane freezes up, terrified of failing An. She thinks “I’m just dragging you down”, starts avoiding everyone. ​
• An feels betrayed, thinks Akito only ever used her. She stops caring about music, says “What’s the point of being the best if no one’s with you?”. ​
• Toya gets pulled back into his classical family, forced to quit street music. He feels “I don’t belong anywhere either”. ​
• Result: They fight, split up. Street Sekai becomes silent, no music, only cold wind and empty speakers.

🎪 Wonderlands×Showtime — The magic dies

• Emu’s grandpa’s dream feels impossible now. She forces her smile until it breaks, cries “If I can’t make people smile, what am I for?”. She closes the amusement park forever. ​
• Tsukasa’s pressure to be “perfect” crushes him. He stops acting, says “I’m not a star, I’m just faking it”. ​
• Nene hides even more, refuses to sing or perform: “I’m useless unless you push me — and you don’t care anymore”. ​
• Rui is blamed for everything, thinks “My ideas only hurt people”. He stops inventing, leaves. ​
• Result: Wonderland Sekai fades, rides rusted, colors washed out, laughter gone. It’s just an empty park.

🎵 Virtual Singers & The Whole World

• Miku, Rin/Len, Luka, KAITO, MEIKO start changing — they get sadder, quieter, more desperate. They can’t guide anyone anymore; they start fading too. ​
• The “Untitled” song that brought them to Sekai becomes distorted, scary, painful to hear. ​
• All Sekais start merging and crumbling — the dark fog from Nightcord’s world spreads everywhere, swallowing light, color, sound, hope. ​
• The line between Sekai and real world blurs. People in Shibuya start feeling the same emptiness, sadness, hopelessness. Music everywhere becomes sadder, quieter… until almost no one makes it anymore.
