"Touhakken (Wisteria Punch or Power Paw)" could be a melee attack which knockbacks all enemies in front of renamon, which could be synergized with "Kosengeki (Fox flash attack)"
which in this case could be a target point spell that charges a set towards the target point or until renamon hits an enemy, where it deals damage and adds a fitting debuff. (Slow, armor reduce, DoT, you name it
"Kouhenkyo (Fox Change Void)" can be a simple target spell that swaps the units positions. (For inspiration, see Netherswap in DotA) This is highly tactical in a dodge game, but charge spells needs to be triggered not to bug in this case.
Izuna (Rice Cord or Spirit Strike) - Summons 4 mystical fox spirits that are imbued with the powers of fire, water, wind and lightning that obey and fight for Sakuyamon.
This could either be based on locust swarm(channeles or not), or be four spirits lashing out towards different angles.
Kongoukai Mandara (Vajra Realm Mandala or Amethyst Mandala) - Creates a huge ring of golden energy that surrounds an enemy and slowly decreases in size, crushing it.
A target point spell that creates a golden ring(yellow aura buff?) which makes enemy units inside unable to move and decreases in size. Every second the enemies take damage and as the ring grows smaller the damage grows higher. Whenever a unit comes outside of the ring it will be able to move again(Ex. a unit is trapped on the very outside of the ring, it will soon not be inside the ring anymore). Lasts about 4 seconds.
Crystal Sphere [Finish] - creates a rune around Sakuyamon, which pauses enemy units inside it. After 2 seconds Sakuyamon conjures a green sphere which blocks enemy attacks and damages anyone inside it, also pushing them out of it.
That's the ones i can think of now.
