If you choose to increase Koo’s capabilities in Beast of Reincarnation, then improving his Rapport rating must surely be one of the first things you need to do. Getting on well with Koo will provide you with additional skills and make him extremely valuable in combat situations. Fortunately for you, it’s not really difficult to improve his Rapport. In this guide, we’ll show the best ways to increase Koo’s Rapport, what causes you to lose Rapport progress, and how to unlock the petting feature.
How To Increase Rapport With Koo

In order to increase your rapport level quickly in Beast of Reincarnation, it is important for you to develop your rapport with Koo. Each of them requires a special method to develop their rapport level. Here is how you should do it for each of them. In the case of Koo, the process is extremely easy. All that you have to do is keep him with you on your journey through the game.
The simplest method that can be used to improve Koo’s Rapport is to treat him well. Every interaction that takes place will build your rapport with him and offer you a number of rewards. It can be done through feeding Koo, bathing him, playing with him, and providing him with treats. Every time Emma feeds herself, she also feeds Koo, and that will improve his Rapport as well.

Make sure to do both regularly, as they’re quick and easy ways to build your relationship with him. In order to give Koo a bath, you must head back to your base at the Cleanse Walker once you have defeated the first boss, find the bathroom, and then interact with it in order to give Koo a bath and increase your rapport. Once Koo’s Rapport increases, he will get more skill slots, making him more powerful in battle.
How To Lose Rapport With Koo
When battling, be careful since losing Koo means losing some Rapport progress. However, there’s no need to worry since you will not lose any Rapport rank that you’ve achieved. What you’ll lose is progress towards the next Rapport rank. For instance, when you’ve gotten to Rapport Rank 3, you will still remain on Rapport Rank 3 despite losing Koo; however, you’ll need to regain some of your progress to get to Rank 4.
How To Unlock Petting
Petting Koo will be unlocked once you defeat Rangifer for the first time and complete the short flashback that follows. After that, pet Koo anytime you are inside the Cleanse Walker. To pet Koo, just approach him until the interact option pops up. Then interact with him and select the Stroke option on the menu. It is an easy and fast way to boost Koo’s Rapport.
