The rematch between Yuu and Kiri is
short and sweet. It also gives us a bit a perspective into how Kiri
see the actions of Yuu and the others. That she believe there isn't
only two choice, that even though choosing to become a dragon isn't
favorable but it still more favorable than death. However to Yuu what
is important is choice that if you choose to live as a human than you
should see that through to the end. This also leads to Yuu choosing
what Kiri is sense she could never decide which she was. That with
Yuu almost killing her but choosing not to gives him his answer. That
Kiri is human and with that she leaves for now.
Then once tear is safe once more Yuu
explains who Honoka really was, and Kiri's believe that the Basilisk
could see the future. This leads to Mistuki forming a flexible plan
to deal with the Basilisk. That in the end they use this bomb as more
of a shield than a weapon. This allows them the exhaust the Basilisk
while at the same time getting close enough to finish it off. Then
with this all that remains is for them to return to the island.
Things end with Yuu telling Iris about his memory loss, and with that
Iris promise Yuu that if he forgets them she will remember for him.
Then with that they return to their everyday life, and things end
with the beginning chapter to this story concluding with it feeling
that there is more to come, since not a lot of the other characters
have been explored so this isn't the end by a long shot.
