Tsukune and Moka and the gang that come to their rescue get caught by a doppelganger and a giant spider demon. Tsukune ghouls out and shows his friends that he is far more dangerous than the enemies that have them captured.
The second arc centres around Moka's sister Koko who eats some magical candy to make her instantly grown up in order to defeat some school bullies. The effects wear off in 13 minutes though, but instead of reverting back to her normal self she becomes a little child.
Stunning artwork and a great fun story make this volume as much of a delight as the rest of the series.
