There is Jean and there is Hikigaya. Even though they are far away they could still see what had happened to Kaiju.
Jean who saw this could not help but say
'What a weird sword'
Hikigaya who is now pacifying the world, changing reality to illusion also has his eyes on the end of the battle
He also saw that sword
And what he said was
'What a sharp sword'
Both of them did not expect the battle to end like this. In this matter, these two are like other people in the world.
They never thought that Katarina would make such an attack. And that attack to work.
But unlike the rest of the people in the world, they see the tricks. Of course, to them it doesn't matter how she does it
What matters is that she did.
