-->''Being a smart student, it certainly shouldn't have surprised Jun that he'd be accepted for a programme that gave the school a chance to show off their work. That is to say, if he actually did sign up for the programme... which he didn't.''
-->''This ultimately left only one possible explanation. One that the magus in training was all too happy to bemoan in his mind: '''"Riko-nee."'''''

* '''Main Character:''' Johnathan "Jun"

!!Tropes
* BloodMagic
* BloodyMurder: Acompanied by ShockAndAwe.
* BoobyTrap: [[Film/HomeAlone Kevin Mcallister]] [[JustForFun/XMeetsY + magic]]= Jun's house. It's been hinted that his room back in the mansion is like this as well
* BreakTheBadass: Minor example. When [[TheStoic David]] tries to interrogate Jun for the third time, threatening the Masquerade. [[HannibalLecture He quickly turns it around]] starting with [[CrypticConversation dropping hints about the magic world]], [[spoiler: pulling a WhatTheHellHero about [[HopeSpot keeping Kai and Riku's hopes up]] about their father, despite knowing he's about to trun into a chiropteran,]] [[AwesomebyAnalysis figuring out that David's]] [[DisappearedDad father had died]] in an incident that also involved chiropterans, then [[KicktheDog using that information to]] [[WhatTheHellHero pick at his psyche]], and "then" unknowingly reminding David about Saya's BerserkMode and that he might just trigger it, before Jun decided he'd done enough to get the information he needs. Sure David might not have broken down, but boy [[NotSoStoic did he get pissed]].
* CallBack: During the Fate/Clan Wars series, [[BlackKnight Kiritsugu as Servant Rider]] weaponizes [[MookMaker his ability to create]] [[EldritchAbomination monsters]] [[LethalChef whenever he cooks]] to get an advantage. Jun had one made, just so it can be[[BoobyTrap sealed inside his fridge, in case someone else but him opens it]].
* ClipboardOfAuthority: Taken up to eleven thanks to the runes Jun placed on [[CrazyPrepared all of his shirts]]. [[http://forum.fanfiction.net/topic/88086/54746505/21/#55819268 As shown near the end of this piece.]]
* CurbstompBattle: When Kai tries and utterly fails to fight Jun in a fit of anger for being left out of the operation. It's stated that he would have met the same result trying to fight David, who was his original target.
* DoesNotKnowHisOwnStrength: Inverted. It's not that Jun doesn't know how strong he is, it's that he didn't know how weak his enemy was.
* ForScience: Jun's reason for observing Saya. Though true, [[CassandraTruth no one who has noticed it believes him]].
* HannibalLecture
* HeroicBSOD: Saya has one sometime after the second chiropteran.
* HiddenInPlainSight: A camera, and listening device, disguised as a bust. The disguise didn't work though.
** Also, Jun when he's using his stealth runes, to an extent.
* ImpaledWithExtremePrejudice:[[spoiler: The first chiropteran by Jun. The second by Saya]]
* InterspeciesRomance: [[spoiler: Based on a entry for Emiya Clan Grand Prix, Jun will enter a relationship with Diva. Which makes it ironic, since his mother hates vampires]]
* InvisibleToNormals: The effect of Jun's stealth runes are essentially this, though conditions do apply. To everyone else, it's a huge giveaway.
* MundaneUtility: Many of Jun's mystic codes.
* NewTransferStudent: How the whole thing started off.
* ObfuscatingStupidity: [[spoiler: It's been shown in the interlude chapters that Nathan knows about magic, as opposed to his compatriots]]
* OurVampiresAreDifferent: The different types existing in the EC are even mentioned here.
** For the record the three are: [[Manga/RosarioPlusVampire Methunselas]], [[{{Franchise/Nasuverse}} Dead Apostles]], and said [[Anime/BloodPlus Chiropteran]].
* ReverseGrip: So far, only once.
* ShockAndAwe: [[CoolSword Favilla]] [[BloodMagic Sanguinis]], Jun's only offensive mystic code.
* ShoutOut: Jun will, at times, quote famous lines from the [[Literature/SherlockHolmes Sherlock Holmes book series]]. It's also been mentioned that one of his former classmates is a [[Manga/ThePrinceOFTennis high school tennis player named Eiji Kikumaru]].
* [[spoiler:SparedByTheAdaptation: George lived and got to stay human for a little while longer. [[InSpiteofANail he's still going to turn into a chiropteran though]]]]
* StalkerWithACrush: What Jun is mistaken to be in the beginning.
* StealthPun: Like Saya's sword, the blood grooves on Favilla Sanguinis are also meant to carry blood. Just not for the same reason.
