The Geisters are launched into action when Siliconian creatures attack a pioneer camp and a Shioru caravan, and the Geisters lose one of their own! It is not the best start for the elite fighting force, but not everyone is troubled by this the way they should be. Is there a traitor in Dobias?

Meet Shai Tanna, newest member of the Geisters. Shai has no time for fun and games, she's just ready to kick ass and take names, maybe a little too ready! Shai's actions leave the Geisters open to second guessing by the Dobias Senate, particularly Elecia Juno, twin sister of inamura, who has her own plans for the Geisters.

What should be a routine rescue and recovery turns into anything but! The Geisters use the powerful "Armored Arm" for the first time, to less than spectacular results. Meanwhile, Elecia stirs up the Senate with some disturbing information about a new breed of Siliconian - "The DNA Eater"!

The Geisters are on trial on the floor of the Senate. Dean and Shai bear the brunt of the accusations with no help from Alcion who has his own agenda. Meanwhile the Shioru plot against the Dobias, and only the Geisters stand in their way. But can the Geisters put their differences behind them and stand as one?

Elecia and Inamuna clash over "Evolution X", while the Geisters begin their training in the "Bio Suits". Alcion's problemed childhood gets in the way when he has to stop a Siliconian from destroying part of the city. Who will do more damage the Siliconian or Alcion?

Cris Vesta's tragic past is revealed as we learn about the death of her older brother and her decision to join the Geisters. The Bio Suits are tested for the first time and Alcion's reactions is not what was expected. Victor's strange behavior is called into question by Cris.

The Bio-Suit testing continues. The Shioru resistance decide to up the ante against the Dobies with the Geisters caught in the middle. Meanwhile Elecia reveals that there is a new threat of Dobias and only Evolution 'X' can save them. But is it worth the price?

The Shioru resistance set a trap for the Geisters. Dean and Shai are left behind to take on the Mulkia Knights. A strange voice in Dean's head seems to be his guardian angel...or is it leading him further into the hands of the enemy?

Alcion and the rest of the Geisters return to base but Dean and Shai are still on their own. Inamuna seeks out Colonel Lanbolt and Dean's guardian 'Angel' is revealed. Meanwhile Alcion has become Elecia's project.

Dean and Shai are back safely from their fight with the Murcia Knights, but Alcion remains distant from the Team as he grows closer to Elecia. Inamuna is engaged in a power struggle with members of the council loyal to her sister. The Geisters are dispatched to save a mining colony that has been attacked by the Soliconians, but Alcion decides to make the fight his own!

Alcion leaves the Geisters. While the fate of Evolution X is debated in the Council, Neftus Saraka is assassinated and Shai is placed under arrest for murder. It is up to Dean and Cris to save Shai as the evidence against her is overwhelming...her knife is found at the scene of the crime!

The house of Vesta and the house of Sarakia are at war! Dean and Shai escape to the one place they will never be found...Shirou. Dean gains a new understanding of the Shirou people. Back in Dobias Victor is missing while Alcion has become Elecia's personal army.

Season 1 comes to a close with the Geisters in tatters. Dean and Shai are still hiding in Shirou. Cris takes her place as the head of the house of Vesta. Alcion is wearing the Megasuit for Elecia and Victor has his own unknown agenda. Will the Geisters survive?
