闇堕ちラスボス令嬢の幼馴染に転生した。俺が死んだらバッドエンド確定なので最強になったけど、もう闇堕ち【ヤンデレ化】してませんか？ • میں اُس ولن لارڈ باس دوشیزہ کے بچپن کے دوست کے طور پر دوبارہ جنم لیا جو تاریکی میں گر جاتی ہے۔ اگر میں مر گیا تو برا انجام یقینی ہے، اس لیے میں سب سے طاقتور بن گیا... لیکن کیا وہ پہلے ہی تاریکی میں نہیں گر چکی (اور یانڈیرے نہیں بن چکی)؟ • Main us villain last boss doshiza ke bachpan ke dost ke taur par dobara janam liya jo tareeki mein gir jati hai. Agar main mar gaya to bura anjaam yaqini hai, is liye main sab se taqatwar ban gaya... lekin kya woh pehle hi tareeki mein nahin gir chuki (aur yandere nahin ban chuki)? • Eu reencarnei como a amigo de infância da vilã que caiu na escuridão. Se eu morrer, é garantido que terei um final ruim, então me tornei o mais forte... mas ela já não caiu na escuridão [e se tornou yandere]? • Me reencarné en el amigo de la infancia de la villana que cae en la oscuridad. Si ella cae, es un final fatal garantizado, así que me convertí en el más fuerte... ¿Pero acaso ella no había caído ya en la oscuridad [y se había convertido en yandere]? • M-am reîncarnat ca prietenul din copilărie al domnișoarei antagoniste care cade în întuneric. Dacă mor, finalul rău e garantat, așa că am devenit cel mai puternic... dar nu cumva a căzut deja în întuneric și s-a transformat în yandere? • Tái Sinh Thành Bạn Thuở Nhỏ Của Nữ Phản Diện Trùm Cuối Đã Sa Vào Bóng Tối, Nếu Tôi Chết Thì Chắc Chắn Sẽ Là Bad End. Thế Nên Tôi Đã Trở Thành Kẻ Mạnh Nhất, Nhưng Chẳng Phải Cô Ấy Đã Sa Vào Bóng Tối [Và Biến Thành Một Yandere] Rồi Sao?

“If you were to disappear… I might just lose myself.”

Arcs is reborn into the world of the wildly popular otome game Celestia Kingdom. He thought he was just a background character—until it's revealed he's actually the childhood friend of the final boss! Determined to avoid the bad ending, he throws himself into his daily life as her servant. But it seems the true cause of her descent into darkness is… her childhood friend!?

So Far it's Been Decent But I Do Love a Yandere So My Opinion Might Be Biased

It's Been Decent So Far Mostly Right Now The Updates is Making This So Slow Like a Month or Two For a Chapter Especially How its Been Pacing At Moment But I See The Potential So For Now I Would Recommend its a Short Read Anyway At The Moment So Doesn't Really Hurt To Give a Try I Just Love That FMC is Yandere
