Tanjiro Kamado Japan ke snowy pahadon mein apne parivaar ke saath ek shaant aur simple zindagi jeeta tha. Apna guzara wo charcoal bech kar karta tha. Lekin ek din jab wo ghar lautta hai, uska poora parivaar ek raat mein khatam ho chuka hota hai — demons ke attack mein. Sirf uski chhoti behan Nezuko zinda milti hai… lekin wo ab demon ban chuki hoti hai. Tabhi ek Demon Slayer, Giyu Tomioka, wahan aata hai Nezuko ko maarne ke liye, lekin Tanjiro usse bachane ke liye takra jaata hai. Giyu ye dekhkar hairaan ho jaata hai ki Nezuko apne demon instincts ko rok rahi hai. Wo Tanjiro ke potential se impress hota hai aur use Sakonji Urokodaki naam ke aadmi ko Mt. Sagiri par dhoondhne ko kehta hai. Tanjiro aur Nezuko pehle apne parivaar ko dafnate hain aur phir nikal padte hain ek naye mission par. Training Aur Final Selection: Mt. Sagiri pahuchkar, Tanjiro ek demon se ladta hai par use maar nahi paata. Tabhi Sakonji Urokodaki aata hai, aur uski resolve test karta hai — usse ek dangerous pahad par jaane ke liye bolta hai jahan har jagah traps hote hain. Tanjiro ka test clear ho jaata hai. Uske baad shuru hoti hai 1 saal ki intense training, jisme wo Water Breathing aur Total Concentration seekhta hai. Final Selection dene se pehle, Sakonji use ek boulder ko kaatne ka impossible task deta hai. 6 mahine tak kuch nahi hota, phir do spirits aate hain — Sabito aur Makomo, jo pehle Sakonji ke students the. Unki madad se Tanjiro boulder ko kaat deta hai. Final Selection Aur Pehla Mission: Final Selection mein Tanjiro ko 7 din tak demons se bhare jungle mein survive karna hota hai. Wahan wo Hand Demon se ladta hai, jise uske mentor ke pehle students ne nahi hara paaye the. Tanjiro use hara deta hai aur Final Selection pass kar leta hai. Usse black color ki sword milti hai (jo rare hoti hai) aur uska pehla mission milta hai — ek gaon mein jaake young ladkiyon ki disappearances ki janch. Wahan wo Swamp Demon se ladta hai jiska body teen parts mein divide ho sakta hai. Nezuko bhi ladti hai aur Tanjiro use hara deta hai. Muzan Ka Pehla Encounter: Tanjiro Asakusa jaata hai jahan usse wo khushboo milti hai jo uske ghar ke qatl ke time thi. Usse pata chalta hai ki ye aadmi koi aur nahi, balki Muzan Kibutsuji hai — sabse pehla aur powerful demon. Muzan public mein ek aadmi ko demon bana deta hai aur bhaag jaata hai. Tanjiro ki madad karne ke liye do demons aate hain — Tamayo aur Yushiro — jo Muzan se alag soch rakhte hain. Tamayo ek cure banana chahti hai Nezuko ke liye. Phir Tanjiro par attack hota hai — Susamaru aur Yahaba ke dwara, jo Muzan ke aadmi hote hain. Tanjiro aur Nezuko unhe harate hain. Zenitsu aur Inosuke ka Entry: Tanjiro ek annoying ladke Zenitsu Agatsuma se milta hai, jo ek ladki se zabardasti shaadi karna chahta hai. Fir wo dono ek drum mansion mein jate hain jahan Inosuke Hashibira, ek wild boar mask pahne ladka milta hai. Teenon alag-alag demons se ladte hain. Tanjiro Kyogai naam ke demon ko hara deta hai jiska dream ek writer banne ka tha. Spider Mountain Arc (Mt. Natagumo): Next mission mein teenon jaate hain Spider Family ke forest mein. Ye demons dusre Demon Slayers ko puppet bana ke control kar rahe hote hain. Tanjiro, Zenitsu aur Inosuke teeno apna best dete hain. Zenitsu ek baar fir behosh hokar Thunder Breathing ka use karke jeet jaata hai. Rui, Lower Rank 5 demon, Nezuko ko apni behan banane ki koshish karta hai. Tanjiro apni Hinokami Kagura technique ka pehli baar use karta hai. Nezuko apna Blood Demon Art ka istemal karti hai. Dono milke Rui ko hara dete hain — lekin pura sach baad mein pata chalta hai ki usne khud ko decapitate karke bacha liya tha. Hashira ke Saamne Trial: Tanjiro aur Nezuko ko Hashira, yani top Demon Slayers ke saamne le jaya jaata hai. Wo log Nezuko ko maarne ka faisla lete hain. Lekin Tanjiro apni baat rakhta hai aur Kagaya Ubuyashiki, Corps ka leader, unhe bachata hai. Sanemi Hashira apne khoon se Nezuko ko tempt karta hai, lekin Nezuko control mein rehti hai — sabke doubt door ho jaate hain. Butterfly Mansion Training: Tanjiro, Inosuke, Zenitsu teenon Butterfly Mansion mein recovery ke liye jaate hain jahan unki training hoti hai. Wahan wo Kanao Tsuyuri se milte hain, jo bahut strong ladki hoti hai. Tanjiro usse emotionally help karta hai apne decisions lene ke liye. Tanjiro apni breathing ko aur strong banata hai — Total Concentration Constant seekhta hai. Flame Hashira aur Mugen Train Setup: Rui ki maut ke baad Muzan Lower Rank demons ko bulaata hai aur sabko maar deta hai, sirf Enmu ko chhodta hai jo ab next mission mein Tanjiro ka enemy banne wala hota hai. Tanjiro, Zenitsu aur Inosuke ko apna next mission milta hai — ek moving train jisme log gayab ho rahe hain. Wahan unka saath dene aata hai — Kyojuro Rengoku, the Flame Hashira. Train ke andar ho chuki hai Enmu ki entry… aur shuru hone wala hai Mugen Train
