! Kenstar

* TheHero
* LargeHam
* PointlessBandaid: On his nose.
* StockFootage: Most of the time he's portrayed using the exact same frame of animation, and always with the same expression on his face.

! Yusuke

* AttackAttackAttack: His usual strategy is to attack head-on. It never works.
* ButtMonkey: The only person he ever beats is Galacticamaru.
* HeelFaceRevolvingDoor: He switches sides ''twice'' in three episodes.
* HotBlooded
* TheLancer
* NotSoHarmless: Yusuke getting defeated effortlessly becomes a running gag, but then again he ''is'' the one who knocks out ''Galactamaru'' with a single punch.
* RedHeadedHero
* ShonenHair
* TheRival
* TheWorfEffect: At one point, he loses to ''stairs''.

! Kotomaru

* {{Bishounen}}
* HeyItsThatVoice: Okay, so it's not ''really'' DavidHayter as [[Franchise/MetalGear Solid Snake]], but he has the exact same voice.
* HongKongDub: Easily the biggest offender. His lip flaps don't even ''try'' to sync with his voice.
* PersonOfMassDestruction: Capable of destroying a WHOOOLE kitchen.
* TheSmartGuy
* TheStoic
** NotSoStoic: Getting called out on his constant shooting of people in Episode 3 finally has him FreakOut.

* NonActionGuy: [[InformedAbility Despite how played up he is in the first episode]], he's the only person in the party (aside from Girl-chan) to not do ''anything at all'' the whole series.

! Girl-chan

* TheChick
* FlatCharacter: Even compared to the rest of the cast. All we know is that she loves Yusuke, doesn't like Swirly Glasses, and has [[GagBoobs huge boobs]].
* GagBoobs
* {{Gainaxing}}
* MsFanservice: Parodied.
* SupportingProtagonist: Despite her name being right in the title, she doesn't do anything and only makes a handful of appearances.
