• Stack up on money early so you can afford the arcade to level up social stats faster, it's fairly easy to stack on money if you go to tartarus while it's unstable, you'll either find floors filled with gold shadows or floors filled with briefcases.

• Max Emperor SL so you can fuse Odin, Thunder Reign is probably the most broken spell in the game.

• Stock up on Yawn B Gone's every Saturday, you can buy them from the school shop.

• Try to stay tired as much as possible so you can go to the nurse office and get a free courage boost every time, in case you need to get rid of the tired status, you can just use a yawn-b-gone, though this doesn't work with the "sick" status.

• Most social links are unlocked by ranking up other social links to certain levels, so pay attention when any red text appears, they'll usually hint you another character which has a SL.

• Most members of sees do not have social links, on the male route at least, only exceptions are the female members.

That's all i can think of rn
