Hajime no Ippo Vol. 143

WBC World Lightweight Title Match – Round 6.
As the bout rages on, Rosario arrives at a moment of clarity, almost as if he’s had an epiphany: “Boxing is fair. Your fists never betray you.”
Meanwhile, Mashiba, determined to show his gratitude to those who’ve supported him, rises once more even in the face of adversity.
Is the moment of judgment near? Who will be condemned—or crowned—in this fateful clash?

4th place: Zatch Bell! 2 Vol.5

The fierce battle to decide the new king of the demon world—where 100 demon children fought—has finally ended.
But soon after, the demon world is on the verge of collapse due to mysterious invaders. The demons lose all their magic, and even the magic books that harnessed human emotions to cast spells are burned away.
In the midst of this despair, demons and humans meet again—and once more, they fight side by side.
