In the Sealed Sword, characters talk to each other during the battles, known as support. Supports raise trust among the characters. There are three levels of supports, namely A, B and C. A is the highest and C is the lowest. Each character is capable of having 5 supports in total, desregarding whomever they talk to. Supports can only happen when the characters are standing next to each other.

The following table shows the characters who can support each other. The more shown means the support is more difficult to achieve.
