Chise Asukagawa (飛鳥川ちせ Asukagawa Chise) is one of the main characters of SSSS.DYNAZENON. She is a seeming delinquent who prefers to skip school and hang out with her cousin Koyomi Yamanaka, but gets caught in the crossfire between Dynazenon and the Kaiju.
Chise used to attend Ayame Middle school, but had a hard time fitting in. She eventually decided to leave.
Skipping out of school one day, Chise was hanging around with her cousin Koyomi Yamanaka and watching the news. A report about floating buildings and card got her attention, so Chise convinced Koyomi to go outside with her to take a look for themselves.
Upon arriving, the Kaiju Shalbandes appeared in the city. Gauma had summoned Dynazenon, who took in him, Yomogi Asanaka and Yume Minami as its pilots, but was one short and took Koyomi, who was standing nearby. Chise was left on the sidelines and called her cousin to check on him. Eventually, Dynazenon changed into Dynarex and finished off Shalbandes, saving the city for now. Chise follows the other pilots during their pilot training to watch them. While ding so, she encountered a strange pearl-like object that she kept to herself.
When Yomogi caught a cold, Chise tried to pilot Dynasoldier in his place to fight Didoras, but had a difficult time doing so because of her lack of training. She had switch back out with Yomogi so that they could finish off the Kaiju, and promised that she would train and do better the next time.
After a while, Chise started to notice that the pearl she picked up from before had started to grow. Goldburn, who understands her commands. Chise initially attempted to hide it from Gauma and the others, but eventually Goldburn grew too large to fit in the luggage she put it in. Later, when Gibzorg attacked, Chise went to find Yume at the floodgate, depressed after hearing about Kano's death from Futaba. She almost fell into the floodgate, unable to be caught by Dynasoldier, but was rescued by Goldburn. Chise then commanded Goldburn to combine with Dynazenon and Gridknight to form Kaiser Gridknight and defeat Gibzorg.One morning, it grows into the Kaiju
After Garnix's defeat, life seemed to go back to normal as the Kaiju Eugenicists ran out of Kaiju seeds. Chise once tried to go to school again but found herself unable to step into the premises. Knight and the 2nd inform her that they will be leaving with Goldburn soon, as Goldburn should not exist in a "normal" world. Chise runs off to see Goldburn, who later informs her that Gagula has appeared. Chise watched over the battle and her friends' victory.
Three months later, they visit the bridge where Gauma made his home before Knight and the 2nd leave with Dynarex and Goldburn. Chise ran after them while shouting that Goldburn was the most amazing friend she ever had, and got a dragon tattoo on her arm.
