@Stralvan oh sakai has lots of other uses.
A skill which Makoto received thanks to the blessings of Tsukuyomi: Multifunctional Magic which Makoto relies on a lot. It can be used in various methods: healing others, increase his strength, detection, and many more. He can use it for his weapon. With Sakai, all place under his sakai can be influenced all kind of his ability which he want to, healing, and all kind use belong to Sakai with his power. He can use two proprieties at the same time (like when he uses it with Strengthening and Healing to boost it's healing propriety).
Strengthening : he can bring a ton object. Like tree within muscle of human, he can bring it himself without problem.
Detection and Scanning: He can detect enemy within radius 4 km. He can even see random object from afar. He can also check the effect of an abilities or skills.
Healing: He can heal without chant. It effect on his follower power.
Barrier: His barrier is strong from amateur class even the most strong.
Intercepting thought transmissions: He can intercept thought transmissions within a 3km radius.
