The Last Day of Work for Two Teachers

When the Fencing Professor managed to canalize the feeling he craved, he frowned and shouted:

"<Hanafuda >!"

At that point, Kira's aura gained color, shape, and density, taking on a reddish hue and an almost liquid appearance, and immediately exploded before Luke could hit the man's face. 

As he was suddenly thrown backward, Luke manipulated the <Yggdrasil > in mid-air to make the roots soften his fall. Still, Luke was hurt a bit by falling on the roots, because the branches of this tree were especially tough.

"Arghh! I guess that was dumb to try to be aggressive while I'm totally at a disadvantage." Luke said to himself while he stood up in pain. 'Since I'm out of options, I'll have to use the roots, but that will weaken Vinigo's prison.' 

He looked at Vinigo and saw that the old man was wearing a pained expression and was eagerly trying to get loose, even though some blood was already dripping down the corners of his mouth.
