I like Sera better than all the other girls so far. Shes more practical. Actually shes tied with Haibara, because them two are the only ones who dont act like they have plot armor or some shit. It would be wiser to kill that bomver before he goes crazy, and Haibara is also grounded in reality when she is always against shinichi meeting with Ran or letting himself be known. My least favorite female has gotta to be Kazuha. Even though she practices kendo, ive mever seen her use it when it counts. It seems like shes only there as a romance interest
