The recommended students for starting a relationship are Aomori Mine and Hanekawa Hasumi.
If you put two Aomori Mine, the power of your SIGNI will be higher and they will be less likely to be vanished in battle, so you can build a strong camp. If you have a chance to attack, use Utazumi Sakurako to do so.
The Recommended students for starting a relationship are Hayase Yuuka, Mikamo Neru and Nekozuka HibikiI.
Use Nekozuka Hibiki to make your opponents discard their cards, and use Hayase Yuuka or Tendou Aris to build up your own camp and take control of the game when your opponent's hand is depleted. If you run out your cards too quickly by cost of cards, you can draw two cards every turn by starting a relationship with Mikamo Neru.
The Recommended students for starting a relationship are Kuda Izuna, Asahina Pina and Takanashi Hoshino
Kuda Izuna's ability and Shiroko go well together, so you can easily give [S Lancer] to your SIGNI, and by starting a relationship with Kuda Izuna, you can put them onto the field from the Ener zone, which is very powerful as you can attack firmly every turn.
Make use of [S Lancer] to your advantage and advance the game.
