Maria is gone; she has left Saki a letter explaining her decision. Saki is up against terrible odds - the disappearance of her friends, the fact that her memory may be erased again, and the monster rats might not be on the side of the gods after all!

Saki is the last of her friends of finally to be touched by a Blessing Spirit, but at the Unified Class her skills are lacking. And talk of missing children taken by the trickster cat continues to scare her.

Another student is removed from the roster. Saki uses her power outside of class.

The group has rowed past their designated safe areas in search of monsters. What they find is worse than what they originally imagined.

As the library continues to explain the history of the world, a danger looms in the background.

Satoru and Saki have been split up from the rest of the group and captured by the outside Monster Rat group.

Saki has figured out a way to help her and Satoru to escape, but in their escape they are thrown deeper in the war between the clans.

Satoru is getting tired and his power is waning and the Earth Spider Colony army is much larger than expected. When all seems lost, help comes from an ally that could be much more dangerous.

Two years have passed since the camping incident and the relationship between the friends has changed dramatically.

Saki and friends are looking for Shun but hit road blocks everywhere they turn. After dinner, Saki remembers a name from the past and Maria flies in with some big news.

Saki has found Shun; he has changed dramatically and asks Saki to leave. Her refusal breaks him down and he explains everything.

Saki fears the Ethics Committee is somehow altering the memories of her and her classmates. But when Mamoru has a breakdown, Saki is asked to quit looking for answers.

Saki sits down with head of the ethics committee, Asahina Tomiko. Asahina begins to tell her the other side of the town’s history.

When Mamoru runs away, his friends do what any good friends do - they try to find him. But on their search, they soon discover that they aren't the only ones tracking him.

Saki and Satoru have returned to the village, but upon arrival Saki is ushered to a meeting with the Education Committee. Her fate is now in the hands of the adults who know all her secrets.

While searching for Maria and Mamoru, Saki and Satoru meet their old friend Squealer. He invites them to the new Robber Fly colony where things have changed greatly, but where is the Queen?

Many years have passed; Saki and Satoru have grown and moved their separate ways. But recent actions within the monster rat community have brought them back together.

Many events act as catalysts in an impending war.

Searching for survivors in the hospital, Saki and the group she and Satoru have joined up with discover Yakomaru’s secret.

Someone or something is following Saki and Satoru as they glide down the river discussing what has happened.

As Niimi stays behind to fulfill Tomiko’s last order, Saki and Sataru head toward the Temple of Purification. When they get there they learn the true extent of Yakomaru’s true plan.

Saki receives a gift from her mother, followed by one final request.

Kiroumaru has suggested that they split up to distract their pursuers, but are his intentions noble?

Things become increasingly more complicated after Inui faces the ultimate fate, Kiroumaru is suspected of being a traitor, and Saki has second thoughts about killing the ogre.

After all the scores are settled, ten years go by. Saki and Satoru hope for a better world.
