Lena channels her chakra into her body, taking control of the threads inside his body he manipulates them to tear out from underneath his skin, taking the form of arms, two extra arms just underneath his original giving him four in total. These arms could help her do multiple things at once, including handseals for other techniques. "I can totes throw crap whilst busting out seals."
"Ah yes I know of this, good to know what it's called. Guess I know what it's called. Heart Reaper."
Lena spreads her hands out in front of her, manipulating her threads as they pulse around her body and through her arms, her masks moving along her morphing skin. The threads protrude from her hand in a mass, forming a large wall covering her - showing off her three energy based masks; lightning, wind, fire. They each shoot a stream, a powerful stream of all three elements all at once, expunging a large amount of Chakra (So Much and only 80 Damage).
Lena then releases these masks and has them fly out and around a large bundle of trees, from three different angles forming a triangle from each vector they shoot to the center. Again another 3 elements all colliding in the center covering a large area, exploding into a seemingly unstoppable force. Lena takes deep breaths when the masks return to her body.
"Damn, with all these masks out and about, I could do this S-rank technique, another Earth technique, and another water all at once. That'd be something...Thanks for teaching me these."
