Upon hearing that, Kirito instantly looked down at the two
girls collapsed beside him and hit out with his words, loud
enough for even the knights to hear.

“—I believe you think it's weird, don't you? About why I could
move.”

Chagrin dyed Linel's eyes as the words she had personally
spoken earlier were stolen.

“The two of you fumbled your words earlier. You said all of
the brothers and sisters were ordered not to leave their rooms.
There shouldn't be anyone who can disobey an order within the
cathedral. Hence, that proved you were not actual sister
apprentices since you hadn't abided by the order.”

A prickling pain crawled around his limbs, perhaps because
his senses had started to return thanks to the medicine, but
Eugeo took nearly no notice of it. He finally understood what
emotion was hidden behind his partner's expression.

Despite his usual character, that Kirito—was enraged.
But it didn't seem that rage was directed towards the children.
After all, a considerable level of sympathy could be seen in his
eyes as they were cast down at Linel and Fizel.

“Besides, there're those scabbards on your waists. Those were
made from the «ruby evergreen oak» in the south, right? That is
the only material that would not rot when in contact with these
swords made from the «poison steel from Ruberyl». There was
no way mere sister apprentices could have something like these.
Thus, I chanted an art to counteract the poison before the two of
you got closer. It did take quite some time for it to finish,
though. ...Strength isn't purely based on how fast you can swing
your swords. To sum it up, the both of you were foolish; foolish
enough to deserve dying here right this instant.”

Kirito coldly told the two girls and raised the poison swords
held in his left hand up high.

The two swords traced a green flash as they flew from his
hand, thrown down without any hesitation. They buried
themselves with a dull noise, into the stone floor at the tip of
Linel's and Fizel's noses.

“But I won't kill you. In exchange, watch closely at just how
strong the integrity knights you ridiculed are.”
