Arc 13The Seed Battle and Spider-Cutter
Uesugi Tetsu won the Seed Battle, gained new powers, and began preparing for the coming era while strengthening his ties with Chisa, Nanjō Emi, and the Minamoto Clan. At the Minamoto Clan, he passed Spider-Cutter’s trial and claimed Azure as his blade, then agreed to visit the Sword Saint with Minamoto Shizuka.
- Minamoto Shizuka defeated Uesugi Tetsu in their fierce duel until Minamoto Shinsui’s sword intent restored her resolve, but Uesugi Tetsu used the Hundred-Eyed Demon to win and became champion of the Seed Battle.
- Uesugi Tetsu accepted Chisa as his disciple, taught her with Hundred Eyes, and learned Heavenly Cycle Flame Armor before obtaining Magatsu-Kami’s blood to forge the Myriad Spirit Cauldron.
- Nanjō Emi forged the cauldron inside Uesugi Tetsu, creating a Legendary-grade Myriad Spirit Furnace Core, and left for Hokkaido after appointing Kujo Tsubaki Grand Official of Onmyō.
- Uesugi Tetsu tested the Furnace Core, returned to Edo Castle, and fought its inhabitants, eventually wounding the Fangxiangshi before waking at the Special Affairs Division.
- Katsumi gave Uesugi Tetsu a scroll concerning Two-Shaku-Sama’s freedom and sold him Yaobikuni’s Heart, which strengthened his body and qi sea after he completed its trade.
- Uesugi Tetsu discovered the Black-Skinned Book, consulted Lord Magatsu about its warnings and Two-Shaku-Sama’s possible path to replacing Kami, then traveled to the Minamoto Clan and formed his core.
- Uesugi Tetsu visited Spider-Cutter with Minamoto Shizuka, defeated the trial’s monsters, and declared to Azure that he wanted to destroy Everworld.
- Azure accepted Uesugi Tetsu as his master, and Uesugi Tetsu drew the Super Epic Spider-Cutter before agreeing to visit the Sword Saint with Minamoto Shizuka.
