Happiness and Sorrow
Izumi is happy about the fact that he managed to release his Kingu this time. Even though his mind is full of memes. The reason why his mind is full of memes is because of his dream. There is an after effect after you met the soul of your weapon. This is the after-effects of Izumi. The Memes. But even though his mind is full of memes, you won't believe the happiness on his face. Because Happiness can be found, even in the darkest of times, if one only remembers to turn on the light.
