Chained flames

Chained Flames: SSS-Rank Familiar Trapped in the body of a tiny, hyper-sensitive white fox after escaping a dark laboratory, Solarflare, an SSS-Rank Fire Mage, must hide his true human identity to survive. He forms a volatile, forced partnership with Lyra, a ruthless S-Rank Lightning Swordswoman who despises weakness and cute things. Lyra treats the fox strictly as a high-efficiency weapon to clear high-risk dungeons (Gates), but everything changes when she discovers his ultimate vulnerability: his single, highly sensitive tail.As a cold, no-nonsense professional, Lyra uses this weakness as a brutal disciplinary tool, deliberately squeezing his tail to completely drain his physical control whenever he steps out of line. Together, they must constantly clear deadly dungeons while staying one step ahead of Niel, a corrupt S-Rank martial artist hunting them with anti-magic weapons. Niel intends to turn the fox into a living mana battery, keeping Solarflare's true SSS-Rank identity a total secret from Lyra so he can claim the ultimate prize for himself.
