Someone took their TypeScript generics knowledge and applied it to the most important problem in computer science: categorizing anime characters by gender presentation. Because nothing says "I understand covariance and contravariance" quite like explaining why that cute anime character might be a trap.

The progression is beautiful: simple generic Girl, then a Variant that could be Boy OR Girl (Schrödinger's waifu), then a Boy that implements the IGirl interface (the classic "looks like a girl, sounds like a girl, but surprise"), and finally void—because some things transcend mortal understanding. The BitCast at the end is the cherry on top: when type safety fails you, just reinterpret those bits and pray.

Your type system can't save you now.
