SIS vs BRO

SIS vs BRO is a Canadian YouTube channel starring siblings Karina (born: ) and Ronald Kurzawa (born: ), who are better known online by their own respective aliases, GamerGirl and RonaldOMG.
Their main channel, SIS vs BRO, is where they often collaborate with each other in DIY (do-it-yourself) challenge videos similar to Collins Key. They also upload skits on their channel reflecting their everyday life. 
They also both have gaming channels under the names of GamerGirl and RonaldOMG, separately. 
On March 20, 2021, their main channel took a 2-year hiatus without warning. They eventually returned on September 25, 2022, with a 59 second long short titled "Karina teaches her sister Aria how to make slime. SIS vs SIS". However, Ronald came back on his channel saying they would no longer make videos together as it wouldn't be the same as he is not the little brother everybody would be used to, as he is now taller than Karina and has a deeper voice rather than being shorter than Karina and have a more high-pitched voice. On April 16, 2024, it was revealed that they will make videos regularly again starting April 18, 2024. 
==Family==
===Karina===
Karina is the older sister who is known under several usernames on social media, including Karina Kurzawa, GamerGirl and KarinaOMG. Having been interested in various aspects of social media for a while, she set up her original YouTube channel, Karina Kurzawa (at the time, known as FUNwithKARINA) in November 2015. She uses it for personal vlogging, makeup, shopping and also posts fun DIYs and product reviews, and previously posted toy videos. She also posts a lot about her friends.
In March 2016, she and her younger brother, Ronald, began collaborating on a joint channel called SIS vs BRO. Karina also has a channel exclusively for gaming, named GamerGirl, which was created in April 2016, and mostly publishes Roblox and Minecraft related content. In the ensuing years, she has become one of the most popular young influencers on the platform.
===Ronald===
Ronald is the younger brother who is known as RonaldOMG online. He has been active in the gaming arena from a very young age, and he first ventured into social media when he joined the gaming platform Roblox. Toward the beginning of 2016, RonaldOMG created his YouTube channel, which showcases mainly Roblox gameplay videos, as well as Minecraft and Fortnite: Battle Royale, providing commentary on the progress. Ronald also created a new channel called “Ronald’s Kurzawa”, where he does vlogs and other videos.
His first solo video, 'Minecraft: BLOODIEST NIGHT,' was gameplay on the game’s survival mode. The video soon grabbed the attention of many, and RonaldOMG became a gaming star overnight. In one of his videos, he has played mini games of fellow YouTube star EthanGamerTV.
===FreddyGoesBoom ===
Their dad, Freddy, also has a presence online under the alias FreddyGoesBoom or OMG Freddy. He is often seen featured in challenge videos on the SIS vs BRO channel, many times with his wife, as well as playing with Ronald on his gaming channel, RonaldOMG.
===Mother===
Their mother is not often seen, as she is the one that records their videos for SIS vs BRO, resulting in the rumour that she is camera-shy. She has blonde hair and blue eyes, just like her daughter, Karina. She is always smiling in the videos one can see her. She is called Aga by the others.
===Baby Aria===
The mother recently had a baby girl named Aria. She was born on July 2, 2019. The popular video "Our Mom is Pregnant!!!!" was when their parents announced the news to the kids. They surprised them by giving three tops in a mystery box. One with Karina's merch, one with Ronald's merch and one with baby clothes. Karina first noticed that she was having a baby girl. She was bursting with tears of happiness. Ronald, on the other hand was confused until the end. They were so happy for these forever life-changing news. Now their baby sister is a toddler and can walk but can't talk much. She loves playing with toys as she is a funny and adorable baby who spreads cheer to her family. In December 2020, her family created an official YouTube channel for her called 'Aria Plays' where she unboxes and plays with toys. As of March 2022, she has over 200k subscribers.
