After Silika entered the tattoo to recover, Leo who was using Ren's body felt something in the surrounding area. He closed his eyes and extended his Mana to the area near the city. When Leo found the source of this weird feeling he couldn't help but smile. A large amount of mana was used, and it was used to teleport someone nearby.
"You guys continue training, I'm just going somewhere, to deal with some things." Once he was done saying what he wanted to say, Leo didn't bother to listen to Lara and Hilda's replies as he coated himself with Spirit Aura.
'This body is just barely strong enough so that I can use the weakest version of my movement techniques. Let's see if it can actually handle it.' Leo after coating himself with Spirit Aura took a single step forward, and with that one step he was able to move a few hundred meters away.
Mana makes use of the surrounding elements and manipulates them. Spirit Aura uses the energy within ones own body, and manipulates that into something extreme.
