''[=PhD: Phantasy Degree=]'' (original title: ''Maseuteo Seukur Ollimpeuseu'', lit. ''Master School Olympus'') is a horror-themed comedy/action-adventure {{manhwa}} that focus on the adventures of Sang, a young woman who travels to Demon School Hades in hope of becoming a student there. The thing of it is that the school is meant strictly for monsters, so you can pretty much see the problem there. As the series goes on, we find out there is more to Sang and her motives than meets the eye.

Licensed and released in the United States under {{Tokyopop}}. Ten volumes of the series have been published; however, the manga is currently on hiatus and it is unknown whether the creator will continue it. He seems to have moved on to other manhwas, such as ''Manhwa/DorothyOfOz''.
----
The series provides the following tropes:
* AllGhoulsSchool: The series starts in the demon school, Hades. Sang had to turn herself into a vampire so that she can infiltrate the campus.
* AnArmAndALeg: Cho-Hyun lost one of his arms when the Madosa Guild attacked Zeus. This doesn't stop him from being a good fighter, though, as he managed to battle his 4 students and curb-stomped three of them (the last one were forced to surrender at this point).
* AntiVillain:
** Gelpa the ninja. Despite being a member of the Madosa Guild, he had helped saved Notra's and Noel's lives [[spoiler:on Chang-Chun's request]].
** [[spoiler:Chang-Chun the leader of the Madosa Guild]] is a kind-hearted old man who tries to save Chun-Lang and the others from Madosa's attack when he isn't wearing his power rings.
%%* AttractiveBentGender: Chun-Lang, Sang, Ms Doe...
* AxCrazy: One of Sang's personalities is a {{Hair Trigger Temper}}ed BloodKnight who would readily use his magic to destroy everything in his way.
* BadassTeacher: All the teachers introduced in the Manhwa are more than capable of fighting monsters and lower-ranked Madosa Guild members. Justified as all the schools they teach in (Hades, Zeus and Athena) specialize in fighting.
* BareFistedMonk: Gyo-Hee from Athena is classified as a "Monk" and fights without weapons. Noru, one of the survivors from Zeus, is similarly and hand-to-hand combatant -- though he is never explicitly stated to be a monk.
* BerserkButton: Most of the main characters, especially Chun-Lang, holds a deep grudge to the Madosa Guild. Mentioning them cause them to go to a berserk rage.
%%* {{Bishonen}}: Majority of the cast qualify but special mention goes to Chun-Lang and Lance.
%%* BlackAndWhiteMorality: Hwee-Young views things like this.
* BlindingBangs: Ryushi has long hair and bangs that covers his eyes. He is also the most mysterious of the Zeus survivors, and is the only one who didn't get curb-stomped by Cho-Hyun during their battle training.
* CantCatchUp: No matter how hard the students try they just can't seem to become powerful enough to take on the Madosa Guild. [[spoiler:Averted in the 10th book were Chan-Chun sees a glimpse of the future were the student finally take down the Madosa Guild]].
* ChekhovsGunman: In the first volume, Notra complains about being tied in an ArrangedMarriage with a powerful demon. Later, in volume 9, her fiancÚ, [[spoiler:apparently the white-winged demon that Noel's mother formed a contract with]], shows up to save her and Noel from the Madosa Guild.
* ClingyJealousGirl: Dustis sees herself as Dagger's lover and accuses him of "cheating on her" when they encounter Sang in the Master Tower. The scene is played for laughs and their "relationship" is never brought up again.
* CostumeInertia: No matter how many times it is torn apart or otherwise lost, Sang is almost always seen wearing a pink hoodie and black pants. She briefly changed out of it during her stay in Elf Town, though.
%%* DarkSkinnedBlonde: Stonia and Notra.
%%* DirtyOldMan: The sage in the Master Tower.
* EarlyBirdCameo: The chapter cover illustrations of the book often feature characters that has not been introduced in-story yet.
* {{Elfeminate}}: Henduh notes that, since all elves are effiminate looking, male and female is almost interchageable. This is apparently how Hexion managed to disguise herself as a guy for so long.
* FanDisservice: When Dev shoots Mahalisa through the chest.
* FantasyCharacterClasses: Apparently, the students in Athena and Zeus are divided into such classes. When she meets a group of Athena students, Sang was introduced to a Knight, a Monk, a Thief and a Mage. Later, she was recruited by the remnants of Zeus survivors, which consists of a monk, a swordfighter, a mage and a healer.
* ForcefulKiss: Sang, while in "his" AxCrazy personality, saw a female Chun-Lang tame a Gigantes, immediately falls in love and kisses her. Chun-Lang did not take it well.
* GenderBender: The [[[RingOfPower power rings]] introduced in the series allows the characters to switch gender whenever it is worn.
* GottaCatchThemAll: Sang and the Madosa guild are seeking to collect as many power rings as they could for reasons that has yet to be revealed.
%%* HotBlooded: Chun-Lang
* HoistByHisOwnPetard: When Iris tries to shoot at Hender in a RoaringRampageOfRevenge, Stonia uses her power to turn the magic arrow back on her.
* IdenticalStranger: Chun-Lang and [[spoiler:Chang-Chun with his power rings on]] look exactly like each other to the point Hwee-Young mistakes Chun-Lang for him.
* InLoveWithYourCarnage: Stonia is in awe everytime she sees Henduh's power.
* InTheHood: Sang in the first book, Chun-Lang in his introduction and Second rank Spear.
* KudzuPlot: The story only manages to raise more questions than it answers them as the series progresses. Who is Sang, and what's her relationship with Chang-chun and the Madosa Guild? What are the Madosa Guild's purpose and why do they need the rings so much? And ''what'' does the rings do anyway? Why do Sang's [[spoiler:and Chang-chun's]] RingOfPower give them split personalities? What is the relationship between Chang-chun, Hwi-young and the rest? Really, just about every plot point introduced in the series is left hanging by the 10th volume, and the author doesn't seem interested to continue it anymore.
* LaserGuidedAmnesia: Sang loses memories of her identity after being hit on the head by an unnamed Madosa assassin, and was given a new identity "Limbo" by the residents of Elf Town. She seemingly regains her memories in Master Tower, but a brief time skip reveals that she can only recollect her experience from Hades onwards, and remembers nothing of her past before that.
* TheLoad: Notra hasn't done a single useful thing since she was introduced. Iris and Oedipus as well.
%%* LongHairedPrettyBoy: Chun-Lang, Lance, Sang as a man, basically alot of the male cast qualify.
* MagicPants: Initially averted. When Sang first uses her RingOfPower and transformed into a larger man, her clothes got torn apart. However, when she transformed again, her clothes remained intact, and this fact did not go unnoticed by one of the author's assistants, who mentioned in her Omake that Sang's clothes is "suspicious".
%%* MrFanservice: Chun-Lang, Dev, Fatalis, it's pretty safe to say majority of the males are bait.
%%* MsFanservice: Sang, Notra, Stonia, etc...
* MysteriousWaif: Despite being the main character, Sang qualifies. She's powerful, enigmatic, has a MysteriousPast, is deeply connected with the Madosa guild and possesses at least 5 of the 9 rings they were desperately searching after.
* PostKissCatatonia: After having "her" first kiss stolen by a male Sang (as noted in ForcefulKiss), Chun-Lang goss berserk and goes on a murderous rampage, trying to kill Sang.
* RagtagBunchOfMisfits: The group of monsters Sang meets in Hades -- consisting of a devil, a vampire, a zombie and a werewolf -- are a group underachieving, borderline drop-out students.
%%* RedHeadedHero: Sang
* {{Revenge}}: Chun-Lang, Noel, Notra, Dev, all lost at least a loved one to the Madosa Guild are hellbent on exacting revenge on them.
%%* ShipTease: Notra and Dev, Sang and Chun-Lang, Chun-Lang and Noel, Sang and Lance...
%%* ShonenHair: Dagger in "Combat Mode", Dev, Hwee-Yong, again alot of the male cast qualify.
* SplitPersonality: Sang's personality switches whenever she activates her power rings, and so far we've seen 4 of them: her "default" character is a childish GenkiGirl IdiotHero who is prone to causing trouble, another personality, as already noted earlier, is an AxCrazy BloodKnight who uses explosive magic to cause as many destruction as possible, then there are the adult male and female forms who are calm and cool-headed.
* {{Stripperiffic}}: Majority of the female characters qualify but Mahalisa and Stonia take the cake.
* SuperGenderBender: Inverted. The rings swaps the user's gender, but at the same time, [[PowerLimiter greatly decreases his/her power]].
* SuperPoweredEvilSide: Dev activates his when Henduh kills his brother Fatalis.
* SweetPollyOliver: Hexion is a female elf, who spent the majority of her appearance in a male disguise. When her cover is blown, she looks decidedly more feminine.
* TakingTheBullet: [[spoiler:Oedipus]] dies protecting [[spoiler:Iris]] from a magic arrow.
%%* TheTease: Notra to Dev.
* TookALevelInBadass: After training in the Master Tower, the Athena students re-emerges much stronger than before. And the previously "left-behind" student manages to almost take down both Henduh and Stonia [[spoiler:before the Madosa Guild's reinforcements arrive, and kills them all anyway]].
* WhatTheHellHero:
** Sang often behaves like a selfish brat who likes to order people around, force nicknames on them, and generally does whatever she wants without considering others. Unsurprisingly, Chun-Lang and Notra complains to her about this.
** Chun-Lang gets called out on this by everyone [[spoiler:when he tries to kill Sang]].
* YouCalledMeXItMustBeSerious: Iris is usually very disrespectful towards Oedipus, always calling him "stupid" and "useless". The only time she called him "older brother" is when [[spoiler:he was dying after protecting her from a magic arrow.]]
* YouGottaHaveBlueHair: Noru's hair is blue.
