* AgeLift: Most characters are younger (due to Youkai generally being much older than humans), but one of the biggest examples is Reimu, who goes from being in her [=20s=] to being ''younger'' than middle-schooler Alice.

** Instead of being a BonusBoss or a high-ranking Net Agent, Reimu in this universe is tied to her old roots; a shrine maiden. Her shrine also has a yukkuri statue of herself. And her [=TortoiseMan=] is a reference to her turtle Genji in the PC-98 games. The Hakurei Shrine Comp's gimmick involves the Yin-Yang Orbs as keys.

* LetsPlay: [[https://forums.somethingawful.com/showthread.php?threadid=3927949&pagenumber=1 One in progress right here]].

* AlternateHistory: The battleship exhibit on the cruise ship reveals this. The plaque that talks about the Destroyer "Kongou", notes that America later became "Eurica", and that Japan started constructing a CoolStarship in 1999 and launched it in 2004.

* RandomlyDrops: The Crimson Noise [=AddOn=], in reference to ''Mega Man Star Force 3'', changes chip rewards from S ranks to be completely random. Bosses have their own table of rewards, which is the regular way of getting their chips, but Crimson Noise may give navi chips from regular battles, ''and'' from bosses the player hasn't even encountered yet. The rewards may be based on location, like getting Ran from Engelles Clock Tower in version 0.503e2. And of course, this mechanic is the only way to obtain the delicious [[RareRandomDrop Illegal]] versions of various chips.

%% For trying to find a way to infiltrate ROM, Shangahi first suggests Remilia. Upon asking her, the rich girl states that just because she's wealthy doesn't mean it makes her ComicBook/{{Batman}}, then suggests asking Kumami, who is ''richer''. (Remilia is "fancy house" wealthy. Kumami is "retired mob boss" wealthy.) Kumami suggests a stealth plane, though even she doesn't know which countries are developing them. As it happens, the Insector Kingdom is one of them.

** [[spoiler:Turns out that Lloyd (named Troid in the Japanese version), Alice's father used to be married to another woman, and their daughter was named Rebecca Marga. Both reference Margatroid, Alice's surname in Touhou canon. It's also revealed that Mama Shinki's first name is Mayumi, which isn't actually a reference to [[https://en.touhouwiki.net/wiki/Mayumi_Joutouguu Mayumi Joutouguu]], as this fan game was made before the game Joutouguu debuted was released]].

* {{Synchronization}}: Just like in ''Battle Network'', Alice and Shanghai can achieve this. [[spoiler:And like Lan and [=MegaMan.EXE=], it's because they're actually sisters (well, half-sisters, but still counts)]]. And like in ''Battle Network'', it runs the risk of both dying if one of them bites it, and Rinnosuke calls Lloyd out for not revealing that.

* CrazyPrepared: Reisen carries things like a shaped plastic explosive charge, which she uses to blast open an electronically locked door when ROM attacks the cruise liner, and an ATM-78 Personal Rocket Artillery, for dealing with [[spoiler:Shikigami robots]] that wish to apprehend her and Alice. That said, the latter is one-upped by [[spoiler:Yukari's electromagnetic barrier in her office desk]]. Reisen one-ups ''that'' by having an armor-piercing round ready ([[FridgeLogic despite rockets being armor-piercing by default]]), only for [[spoiler:Yukari to proclaim that she has a lot of Shikigami headed their way, and Reisen surely doesn't have enough ammo to deal with them all, thus requiring Reisen to HoldTheLine against them while Shanghai finds a way to disable the barrier]]. And when it's revealed that [[spoiler:Reisen ''can'' deal with all of Yukari's Shikigami]], turns out [[spoiler:Yukari also has [[VillainTeleportation teleportation technology]]]].

** In [[spoiler:School Comp 2]], [=DruidMan=] attempts to use Life Meteor, a ''Dark'' Program Advance, to delete Sakuya and [=TankMan=] so then the player knows that is a mechanic that exists.

* PurpleIsTheNewBlack: The D-colored [=AddOns=] have a purple Core color, in contrast to R for Red, G for Green and B for Blue, implying that D actually stands for Dark, since like Dark Chips, they're negative.

* RandomlyDrops: The Crimson Noise [=AddOn=], in reference to ''Mega Man Star Force 3'', changes chip rewards from S ranks to be completely random. Bosses have their own table of rewards, and Crimson Noise may even drop navi chips from bosses the player hasn't even encountered yet, even outside of boss battles, like getting Ran from Engelles Clock Tower in version 0.503e2. And of course, this mechanic is the only way to obtain the delicious [[RareRandomDrop Illegal]] versions of various chips.

%% Neither TankMan or SpannerMan are Shanghai's type.

* DebtDetester: When Alice gives Remilia a souvenir from Engelles, Remilia says that it's the thought that counts, and that she doesn't like being in debt:

* DeadlyGas: Downplayed. When Medicine starts tampering with the ventilation system, Alice and Mari think this is played straight, but Marisa corrects them by identifying it as merely dirty air, though that's not exactly healthy either. Inside the air purifier [=COMPs=] however are clouds of KnockoutGas.

%% The Shinki flower bed has a surveillance system that sends its data to mobile devices (like on Shinki and Alice's [=PETs=])

%% The reason TortoiseMan didn't leave while PyroMan was attacking was in order to protect the donation box, a testament to all of Reimu's hard work.
