RYU GA GOTOKU ISHIN
Ryu ga Gotoku Ishin (released in Japan in February 2014) is a spin-off game set at the end of the Edo period of Japanese history (known as the Bakumatsu period), a period when the Tokugawa Shogunate came to an end and imperial rule was restored (Meiji Restoration).
Sakamoto Ryoma is living undercover, with a false identity, as "Saito Hajime" in Kyoto. One year earlier, on the eve of the coup d'état of Tosa, Ryoma's foster father, the man who raised him, was murdered before his eyes. The only lead he had to discover who the killer was is that he used the Tennen Rishin style of fighting. This is a style used by the Shinsengumi, so Ryoma infiltrates their ranks, becoming captain of the 3rd Shinsengumi unit, in attempt to find the killer.

When in squad organisation, the first slot of a squad is the corporal slot. The rest of the slots are regular soldier slots. When you select an empty slot, choose the first option to insert a card.
When you select a slot which already has a card, choose the first option to swap it with another card. Choose the second option to use the "synthesise" option - you can synthesise cards to increase the experience of the base card. Of course, you lose the cards you used to synthesise with the base card after doing this.
Choose the third option to use "rebirth" - you can only do this with a card that has reached its max level. Different cards require a different weapon to use rebirth. After using this, the card's level goes back to 1 and you can level it up again to increase the health and ability gauge refil speed even further.
Choose the fourth option to remove the card from the squad.
Please check out the Soldier Card page for details on the cards, as well as lists of the cards themselves and their abilities.
