Among the codes of Roblox Ro-Ghoul above, there is a code of Roblox IXA & Monster Eto3. That code is Sub2Sagee4. You are able to earn 50,000 Yen once you redeem the code. For those who are not familiar, IXA is the name of the koukaku type quinque of Kishou Arima. This one has two modes: Lance Mode and Gimmick Mode. Meanwhile, Eto can be described as an ukaku that is considered one of the strongest Kagynes in the manga and anime. This thing takes the form of a wing. The wing itself has a Scimitar blade extending from the left shoulder in its first and original form.
How to redeem the codes of Roblox Ro-Ghoul? In order to redeem the code, the first thing that you have to do is to press the foward-slash (/) button on your keyboard to open the Roblox chat menu. Then, paste the code that you copied by pressing CTLR+ V or copy the code exactly as you see it. the next thing that you have to do is to press Enter and send the message chat that will redeem it. If the process is successful, a Dialog Speech Bubble will show up over your character to tell you that the rewards you have redeemed. Apparently, you will have a better chance with successfully redeeming the code if you type it instead of copy-pasting it. Please keep in mind that you cannot use codes more than once. If you have redeemed the code while being a Ghoul or CCG, you are not able to swap to the other side and redeem it again, so please choose wisely.
Aside from those codes that will give you a various amount of RC and Yen, there is a code without a particular reward. The code is !Roziku. The code is able to make your hair green. The hair color (green) was made for the birthday of a Youtuber known as Roball.
