START

Plot
START is about the Elsen left alone in the purified Zone 2 named Elne. Spectres continue to appear throughout the zones, and The Batter recruits Elne to join him in his mission to purify 3 new zones with the promise of helping him find the legendary "Safe Zone".

Main:
-- TRIGGER WARNING, AND MAJOR SPOILERS --

Elne
Elne is an Elsen from Zone 2, being the only remaining resident after the purification. He was given a special sword that allows him to control his burnt form, being helpful in battle. Elne is a very nervous individual and gets scared really easily. He only joins The Batter on his mission because he was promised that there is a safer place for him out there.

The Batter
The Batter is the former puppet of the player (You). He returns to find that spectres have been appearing once again in the purified zones and speculates they're coming from somewhere else. He manages to convince Elne to join him.

The Batter is rather blunt and can be cold towards the people around him. He has no sympathy, not caring what would happen to Daren after defeating the Zone 5 guardian despite Danny's pleas. He only has one goal and that is to finish his mission. He won't let anyone stand in his way.

Danny
Danny is a wide-eyed Elsen with a scar on his eye that lived in Zone 3 before its purification and was relocated to Zone 4. He is very loud and excitable when first met, but during his time in Zone 3, he was quiet and didn't talk much. He is very protective of his twin brother, Daren.

Zone 4 faced destruction when the Zone's guardian, Aeya, decided to give it a complete makeover. This ended up killing many Elsen, including Danny's brother. Danny was relocated to Zone 5 temporarily, where he toughened himself up and grew into a new personality that is seen when he is first met in Zone 4's factory.

Daren
Daren is a wide-eyed Elsen with a scar going all around his neck that lived in Zone 3 before its purification and was relocated to Zone 4. He is a really quiet and nervous person, usually sticking near his twin brother Danny when possible. He suffers from hallucinations and tends to scare easily.

As stated above, Daren was killed in the destruction of Zone 4. However, once Danny was relocated to Zone 5 for a while, he was brought back to life by the Zone 5's guardian Kapali.

Though the resurrection comes with a price. If Kapali is defeated, Daren will die. Danny explains this to The Batter and Elne, but the Batter brushed it off and engaged in combat with Kapali. Kapali is ultimately defeated and Daren dies as Danny was trying to leave the Zone with him.

Aeya
Aeya is the Guardian of Zone 4. She comes across as loving and motherly, but behind that façade, she is cruel and cold. She easily manipulates the residents of her Zone, tricking them into a false sense of security. It's possible that she enjoys being in control and tries to keep the Elsen living there from ruining everything for her.

Kapali
Kapali is the Guardian of Zone 5. Unlike the previous guardian, Kapali has a tough exterior but is a much caring person deep inside. He rules his zone with an iron fist and acts like a mafia boss. However, he was the one who resurrected Daren after hearing about his death. Despite this, The Batter decides to kill him anyway, still seeing him as impure.

Zacharie
The merchant encountered throughout the game. He seems to know way more than he lets on, even stating that he desperately wants to tell Elne something important, but keeps it to himself as it will "spoil the game".
