Sachi Faker

Sachi Faker (사치 페이커, Sachi Peikeo), also known as the "Ticket Hunter", is a D-rank Regular and part of the 3 top predators within the Hell Express. He is apparently the one that Regulars should most be afraid of at the first station. He is currently on board the Hell Express with the main goal of stopping Hoaqin.

History
Sachi undertook the Hell Express when a Slayer candidate gradually killed everyone on board until, in the end, there were only five survivors left; he and three others forfeited when one of the five survivors ended up dying. During this experience on the Hell Express, he, Aka Williams, Boro, Daniel Hatchid and Roen were the five survivors.

Appearance and Personality
Sachi looks much like he did 600 years ago, with fair skin, drooping crimson coloured hair and similar coloured eyes. He currently has a black eyepatch-like thing covering his left eye.

He appeared to be quite easygoing in the past but this has changed into a more serious persona in the present. He seems to blame Boro for Daniel going the wrong way and came to the conclusion to avoid him because of his personality.

Wooden Horse
At the 37th Floor station, Wooden Horse, Sachi arrived with Aka whilst blaming Boro for Daniel taking the wrong path. After being filled in on what Daniel was planning to do, Sachi reflected on his thoughts of when Aka came to find him before saying that he happened to be around thanks to Emile.

At the 'Altar' Boro, Aka and Sachi witnessed Hoaqin coming out of the train with Boro noting that he looked smaller than last time. Boro then watched in dismay as Hoaqin effortlessly decimated a large amount of the Regulars at the station.

Later, with only 10 minutes left to board the train, Boro and company raced towards the stairs of the train but caught the attention of Hoaqin on the way. With freak lightning interrupting Hoaqin's assault, Baam, Koon and Rak swiftly arrived on the stairs leading into the train. Daniel told them all he wouldn't let them on to the train and that they would take control of the train until Hoaqin was whole and Roen was alive. Sachi then said that it was their job to talk sense into Daniel. A brief scuffle broke out between the two sides but it was interrupted when they were all teleported to the train conductor's office. He introduced himself and then informed them about a game that would decide who would become the Slayer candidate in a month's time. At that, he teleported them away to different locations in the train.

A Month
Their group immediately encountered the guardian Yokim and they planned on taking him down until Hwa Ryun suggested that from that point onwards, Baam was to take all tests by himself in order to prepare for challenging Hoaqin. Sachi then watched as Baam took on Yokim and discussed with Boro about Baam's lack of killing intent and how he wouldn't be able to match Hoaqin if he didn't develop it; Baam eventually defeated Yokim and they passed the stage.

During their traversing of the train's pathways, the group eventually encountered the "god" of guardians. Sachi and Boro suggested turning back due to the guardian's fearsome reputation and power, but Baam adamantly decided to stay and challenge the "god" of guardians. At that, the guardian snatched Baam up and took him away. Boro and the others then waited for three weeks for Baam to return.

Eventually Baam hurriedly returned and the group narrowly made it to the 4th stage in time.

The Dallar Show
Sachi and the others listened to the rules of the Dallar Show and then watched as Koon coolly won the first round. During the second round game, "Transferring the sweetfish", Sachi was partnered with Aka and Boro. As they navigated the surprisingly treacherous pipes, the three of them determined that stopping Hoaqin was more important than winning the round.

Powers and Abilities
Sachi is said to possess outstanding physical ability and "special" Shinsoo controlling abilities. Also it is said that he is "absolutely" powerful at "one-vs-many" battles. It is stated that he is among the three strongest D-rank Regulars. He notes that he experimented with "forbidden spells that deal with souls" and lost an eye as a result of a "sin" he committed.
