This reminded me of something interesting: on recent events, event packs are sold on shop, with promotional price. They always have items that are relevant to the current event, and can be seen as hints. Let's take a look in the Osaka Castle Frontlines Pack:

10 Help Tokens 3 Makunouchi Bento 3 O-mamori Kyoku 3000 Steel

Implying: you'll need lots of steel on repairs because you'll use your high leveled swords in the last floors; lots of help tokens, as you don't have the luxury of time to wait like 30h to repair your swords; equip your team with omamori, the danger is real and swords will eventually break; keep your swords in the best health, all sakura-fubuki if possible, it can help you to reach the boss nodes.
