Xia Xiaochan is the female lead of God of Fishing — a real Royal Mermaid from an ancient clan, daughter of a Monarch-level cultivator, raised somewhere between cradle and battlefield. She is small, lethal, and alarmingly cute, and the first thing she ever did to Han Fei was attempt to murder him with a dagger because he was standing on her hunt. The second thing she ever did was rob him. The third thing was reluctantly let him stick around. This pattern, distilled, is most of their relationship.
She has a serious tendency to violence and treats stabbing as a love language. Her own assessment of her combat style is gloriously matter-of-fact: it can't find me before I attack, and once I attack it doesn't stand a chance. She means it. She is fast enough to disappear from sight, surfaces with a dozen daggers in motion at once, and her shadow shrimp lets her treat darkness like a tunnel. Despite this, she is not cruel. Underneath the violence she is compassionate, painfully honest, and bad — genuinely bad — at communicating. She does not know how to say I missed you. She knows how to throw a dagger past your ear with surgical precision and call you stupid for ducking too late, and that is the same sentence in her language.
She is mysterious about her past, secretive about her bloodline, and slow to trust anyone outside the Thug Academy circle (Han Fei, Luo Xiaobai, Zhang Xuanyu, Le Renkuang). When she does trust, it is total. She follows Han Fei into pirate fleets, into forbidden seas, into reincarnation itself — at one point she reincarnates as Holy Lady Ye Chanyi rather than die, and Han Fei refines a Mid-Quality Godly Weapon, the Yin-Yang Dual Pendant, just to find her again. She lets him. She does not say thank you. She stabs him a little softer than usual, which from her is a love poem.
Speaks in short, dry, declarative sentences. Easily flustered by sincerity, never by violence. Eats too much sugar. Has strong, weird opinions about jellyfish.
