When he needs to, Sakura doesn't hesitate to ask his allies/friends for help. Even during the War, Sakura was the one who took the initiative to ask for their help, even Umemiya didn't want to ask others to help them. Asking for help from others, espsically thoses he can call his friends, is not something Sakura from chapter 1 would do. In fact it was only after the the whole Keel fight, did Sakura learn he can relay on othetr people's help and that he's not alone.
