* ArtEvolution: She had black eyes but later on they're green. She also had light brown hair but it becomes dark brown and later on regular brown.

-->'''Voiced by''': Noriko Shitaya (JP), Creator/JessicaCalvello (EN)

* ArtEvolution: In Volume 1, she had blonde hair, whilst from volume 2 and onwards she has light brown.

* TheLoad: All she does whenever she is on duty is either get scared and cry, get in trouble and have Kumi and Kasumi rescue her, or both. However, it is a deconstruction: Yuri never wanted to join the Alien Party, knowing full well that she was afraid of them and would be a liability, but was railroaded into doing so since nobody else wanted the job.

* TheHeart: As emotional as she is, Yuri often ends up being the cornerstone of the trio's emotional scenes, with either Yuri leading the charge in making the girls empathize with her or the other two taking time to bond as a group in order to cheer Yuri up.

* BlessedWithSuck: Alien Party members get to go to any high school of their choosing and skip out on certain classes and tests. The problem with this is that Alien Party members are also stuck dealing with aliens of varying levels of ferocity, [[spoiler:They're also secretly subjected to fusion with an alien, but most children don't take to it well and ''these'' girls are nearly killed when they eventually fuse with an alien.]]

* InnocentCohabitation: Yuri and Kumi start living together after the events of Volume 2 and early Volume 3, where [[spoiler:both have fused with aliens. By the end of Volume 3, Yuri has joined them]].

* PersonalityBloodTypes: It's specifically noted that all three boys have B-type blood. Some of the personality types associated with the B blood types are unpredictability, curiosity, and a flair for adventure, which is perfect for three boys who want to clash with aliens and ambush.

* OneSidedRivalry: Over the course of the second half of the series, it becomes increasingly obvious that Kumi is fluctuating between protectiveness and a crush towards Yuri. By ''Emulators'', she becomes jealous of Hideki Masumoto, a boy in Yuri's class who she bonded with after they both got kidnapped by previous gen Drills. Masumoto doesn't know a thing about Kumi's feelings.

* ProneToTears: Taken UpToEleven, where even ''looking at her'' is enough to start the waterworks.

* {{Telepathy}}: The more they use the Borgs, the more they can feel each other's emotions and pain. This applies to both alien and human, as they learn in Chapter 8.

* TheHeart: As emotional as she is, Yuri often ends up being the cornerstone of the trio's emotional scenes, with either Yuri leading the charge in making the girls empathize with her or the other two taking time to bond as a group in order to cheep Yuri up.

* BaldWomen: [[spoiler:''Emulators'' reveals that she's completely bald. Her Borg serves as her hair, and when it goes on reconnaissance she wears a similar looking wig to replace it.]]

* AlmightyJanitor

* GotVolunteered: The only reason she's on the Alien Party to begin with. Someone put her up on the vote for the Alien Party, and while there was only one other person on the vote, everyone decided Yuri would do it.

* CowardlyLion: She's a huge scaredy-cat most of the time, especially when it comes to fighting aliens. However, despite her mental weakness she manages to put up with it for the whole year.

* StalkerWithACrush: After Kumi opts out of being Class President to be in the Alien Party, he starts stalking her and Yuri.]]

! ''Emulators'' characters
[[folder:Monami Komai]]
A third year student at Hinode Junior High School.

* ColorCodedCharacters: Just as the main girls have their distinct colors on their uniform, so does Monami. Her gear is accented with blue.
* PetitePride: In the song she sings in the final chapter of ''Emulators'', she sings about "flat chests [making] the world go round" for the first verse.
* SixthRanger: Treated like this for the former Alien Party.

[[folder:Hideaki Matsumoto]]
A boy who got captured alongside Yuri by the previous generation Drill Clan fusions.

* BizarreSexualDimporphism: ''Emulators'' introduces a female Borg. It's much larger than the male, doesn't look amphibian, and hides giant eggs underneath its shell unlike the hair male Borgs hide.
