They Are All My Scabbards

(Handcrafted the old-fashioned way, in a crossover world.) Before joining the chat group, Yu Xia Ya was a sword immortal without a sword. But after getting all sorts of sword-wielding beauties, he finally understood: the most physically demanding part of being a sword immortal isn't swinging a sword. Aqua: "Who knocked me out yesterday?" Kazama Kazuki: "Xia Ya, I'm really upset that you're secretly chatting with new girls behind your sister's back!" Ellen: "Um... Xia Ya... I left my pantyhose in your room. Can I come pick them up tonight?" Illyasviel: "Big Brother Xia Ya!! Kuro says Miyu gave you Valentine's chocolate a couple of days ago. Is it true?!" Senya Ruruka: "Xia Ya... you pathetic loser, get up and eat breakfast!" Amakawa Kaoruko: "Xia Ya! You have the nerve to give special lessons to Magenta and Cyan, but not the guts to fight me?" Yixuan: "I observed the stars last night and found that tonight is perfect for you to help me with my cultivation." Takarada Rikka: "Xia Ya, Akane and I bought new clothes. Meet us at the usual place!"
