Plucky Girl: She has elements of this. She has a lot of bad stuff happen to her, but she does not quit. She also displays optimism before going out on missions, unlike pessimistic Glas. She tends to give people the benefit of a doubt, which Glas would certainly not do.
Younger than They Look: She appears to be in her early 20s. However, there is a puzzle in the first game that reveals quite a bit about her age. She was 5 years old when her parents were killed right in front of her. She is currently 18 years old. She will reach the age of 35, and may even get married and have children by then. She will finally become 88 years old, where she will live on the island that the Eight Immortals live in. Then she will die either at age 88 or sometime afterwards. Are you amazed or surprised?
Death Seeker: Well, let's think for a minute. He engages in binge-drinking (more like drinking himself to death). He plays Russian Roulette. He engages in these activities in his spare time. What do you think?
Nietzsche Wannabe: Glas definitely is this. When Hana said that she has faith in Rain not being a back-stabber, he goes off on this rant about how "Faith is for the weak!" Would it have killed him to explain why he thinks that?
Shoot the Dog: He tried to kill the young girl and Anti Anti Christ (Wee Ming) to save the world as well as try to get revenge for Deke's death (that, and Glas seemed to have become mentally unhinged). He shot his brother Drew, but it was an accident. Drew was going to shoot him first (For money and for leaving him with only one arm). Really, Glas should have just punched that whiny brat out.
Hidden Depths: He definitely has this. One of the Eight Immortals reveals to Glas that Rachel Kazra dabbled in Creating Life, and there were a number of failures. A lot of the failures were flesh-eating zombies that Glas and Hana fought against. Deke is one of the failures. The Immortal points out to Glas that Deke is a puppet of greater forces, but that is not explained or expanded on. Besides, he cannot be all bad if he truly likes Hana, Glas, and Rain. He has not tried to kill them at any rate.
Token Evil Teammate: When this applies to a team mostly made up of protagonists listed under Sociopathic Hero, that's saying a lot about how brutal this guy is. Deke ends up as a boss fight in both games.
Physical God: On an important note, her last name is Qin. She is the daughter of 秦始皇 (Qín Shǐ Huáng), the very first emperor of China. The one who burned books and buried scholars in the name of stability in the country. The one who wanted immortality. The one whose tomb contains an army of soldiers made of terracotta. The one who became a god, but is basically in an And I Must Scream state - at least in this game.
