The Life of Kosuzilla Love Live! School Idol Size Stories - Definitive Edition! chapter 5 by GiantessKaijuFan and Ninten

Kosuzu Kachimachi might just have the strangest childhood out of all the members of the Hasunosora Girl’s High School Idol Club. Just saying her first name "Kachimachi" already sounds very giant-monster like in a way, but that is a reflection of how she is in some form.

The pale skinned Japanese girl with greenish brown hair would normally be about 5’0 tall at her age of 15, but there is a massive catch to her in Kachimachi's case. She is actually 200ft tall (60.96 meters)!

How she grew, well she has a rare disorder called "Kaijuotora", which made her grow way bigger than any average girl her age, or any human being for that matter. Kachimachi's true growth didn’t start untl she was at least 4 years old, where she was about the size of her parents. It was an odd sight to see a 4 year old as big as her parents, but her growth would only get even bigger from there. 

Kachimachi's growth spurts would continue over the coming years, happening at random times. They would cause her to outgrow any clothes that she was wearing, which would greatly embarrass her, and at age 5, she was already around 50ft tall. The whole world would be exposed to her, and that is where her life took an even more interesting turn...

Soon, her growth spurts would start slowing down somewhat, but even still, Kachimachi continued to get bigger and bigger. At age 15, Kosuzu Kachimachi's had a confirmed height of 200ft tall.

Of course, this strange disorder would come with all sorts of issues over the years that Kachimachi would have to deal with. And not just her or Japan, but the entire world.

Clothing became a huge issue for her, as she often had to wear specially made bras, panties, and swimsuits made just for her. Normal clothing was too expensive and prone to tearing, she was was used to only being in her underwear or a swimsuit. Kachimachi had to eat copious amounts of food somehow, whether giant amounts of fish, or even some rusted up cars and such. She couldn’t go anywhere normal thanks to her height, and often she had to sleep way far from the city. That is not even accounting for all the things that she accidentally or purposefully crushes with her feet or body on a regular basis. Kosuzu Kachimachi felt like a freak thanks to her height, and while she never failed to do anything that she set her mind to, she worried that she may not be good enough.

However, thanks to her family and Japan, Kachimachi did somehow manage to find a way. She always had a love of giant monster movies and series, especially Godzilla. The big radioactive dinosaur that destroys the city in most movies or fights the monsters without any fear. One time, she was asked to destroy some buildings for Tokyo, and while she was hesitant at first, she did eventually give it a try. She then smashed her hands into some buildings, ripping them to pieces. For fun, Kachimachi even roared the whole time as if she was a kaiju! It was the most proud moment of her whole life, and it made her smile. She realized that she is a giant monster, but that’s fine with her, and she decides to embrace her giant monster identity.

Ever since, the cities of Japan helped even more to adjust to her life of being a giant monster school girl, and recently gifted her a school uniform her size for a school she is attending. Hasunosora Girls High School. Accommodations surely had to be made for her somehow, but she knew she would find a way.

Kachimachi often liked to act like a giant monster as she stomped through the cities, still being mindful of where she stepped, and helping the people in any way she can. She even has her own private "Monster Island" off the coast of Japan which gave her some high tech goodies that she often uses to adjust to being a giant monster. Life is surely good for Kosuzu Kachimachi, or as many call her, Kosuzilla!

(As a joke, she roars anytime that she is called that name)

So what episode of her life should we focus on?
