Contract name (Mrs.Shiburai) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
MrsShiburai.addLiquidity(uint256,uint256) (#672-685) ignores return value by uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#677-684)
Ensure that all the return values of the function calls are used.
