Watching the videos is pretty boring cause all I hear is whisk or add 1/3 cup of water with no other direction. As for cooking with it, I usually just guestimate. Back home my friend got me measuring cups with raised numbers, but I haven't bothered to get anything here cause Rin's usually the one who cooks.
Join the Canvassing branch if you want to fight. But don't put normal people down. It's rude and you'll end up flat on your ass without the support of others. Besides, even if you train to be a hero, that never guarantees you'll end up one.
