I get excited every time a new banner drops, so here’s how I go about unlocking a character like Hanako in 'Blue Archive'.
First, open the Recruit (or Gacha) screen in-game and look for the current pick-up banners. Hanako will only be pullable when she’s featured on a pick-up or limited banner, so keep an eye on the banner name and the image that shows students included.
Second, save and spend the in-game currency and tickets shown for that banner. Use your paid/free premium currency or any student recruit tickets you’ve hoarded. Events sometimes hand out guaranteed draws or exchange currency that can also net you that student, so check the event shop and the news page before you pull. I usually wait for rate-ups or step-up promos to increase my odds, and I follow the official notices and community calendars so I don’t waste pulls. If you miss the banner, be patient — most characters rerun eventually, and planning your pulls for a future rate-up felt way smarter after my last failed 10-pull.
