Often referred to by the nickname "Yellow." Height: 150cm. Short black hair with yellow inner color. Upturned eyes and fangs pointing upward.
A girl capable of calling down yellow lightning. Pink often clings to her for affection, but she finds it embarrassing to be seen like that. She has the temperament of a straight man (tsukkomi). She can be high-energy and is quite caring. She uses a strange shout when dropping lightning: "Joppa-joppa BOOM!!" For rapid fire, it becomes "Joppa-joppa BOOM!! Pa-BOOM!! Pa-BOOM!!" What even is this?
She has a long-standing, love-hate relationship with the Warpmen. She often strikes them with lightning (literally).
Often referred to by the nickname "Pink." Height: 142cm. Short black hair with pink inner color. Smirking eyes and fangs pointing downward.
A girl capable of calling down pink lightning. She often clings to Yellow for affection, but she gets furious if anyone sees them. She is quick-tempered and easily provoked by teasing. She becomes very lively when she's the one doing the teasing. She uses a strange shout when dropping lightning: "Bi-bi-bi BANG!!" For rapid fire, it becomes "Bi-bi-bi BANG!! Bi-bi-BANG!! Bi-bi-BANG!!" What even is this?
She has a long-standing, love-hate relationship with the Warpmen. They tease her constantly.
There are many of them. Height: A tiny 95cm. Light blue hair with two antenna-like feelers growing from their heads. Hairstyles and clothing vary by individual.
Small characters with the ability to warp. There are multiple identical companions. While it takes light 100,000 years to travel from one end of the galaxy to the other, they can travel at superluminal speeds in 10 hours by consuming 0.001 grams of body weight. They tease the Mokumokus and frequently dodge lightning at the last second. They get hit occasionally, but they survive. In fact, when their smartphones run out of battery, they intentionally get struck by lightning to recharge. 腰を左右に振って横ノリで煽ったりする。 They are playmates and more to the Mokumokus.
When speaking, they tend to elongate the ends of their sentences or use katakana-style speech (e.g., "Basically, you're DO-ING GREAT!" "Exceeding the speed of LIGHT!" "Dodging like a PRO, A-MAZING!" "Only move when the lightning STRIKES." "Basically, not so GOOD.")
