There is a ton of truth in what Cromagnon has said. No one can tell you what works for you...but you. Many will try (including me right now)...but ultimately, you have to learn what works for you. And when you find it...dont listen to people telling you what you can/cant do. THEY AREN"T YOU. DO what you know works for you and stay focused.

But quite a bit of it is muscle. And I am currently working on maintaining the lean muscle mass that I have accrued in all of my time of lifting (28 years). I am using a ketogenic diet to cut flab and maintain muscle mass (so far so good, I have dropped 20lbs of flab) and it is working perfectly. I am as strong as I have been in 10 years in the gym...and I work out heavy and with high intensity. For example, my back & arm workout on Monday involved 12 sets of different back exercises with reps in the range of 5-8 and no longer than 30 seconds rest between sets. As well as tricep and bicep work (~8 sets each) to finish off arms. All inside of 60 minutes time. In, out ,done. And I am sore the next day.
Anyway, the point I want to make is the ketogenic (i.e. low carb) diet has been perfect for me to maintain muscle mass AND I HAVE NOT HAD ANY ILL EFFECTS IN THE GYM FROM IT. Seriously, I normally eat <30 carbs a day...and I get nearly all of my carbs from vegetables and nuts. I do not supplement my diet with ANY carbs post workout or ever, and that is truly contradictory to the "research" out there right now. But it works for me. So I do it.
As for gaining on a keto diet....never tried it. Im just curious though....your post says you have been gaining mass on your diet (i.e. 12kg). So, what is your question really about? You have gained mass/muscle with what you have been doing. I think it is working for you. My suggestion would be to continue exactly what you are doing, be patient with it (mountains weren't built overnight...either are huge guns!) and stick it out.
Good luck getting massive!
If you can just get your....mind together....then come on across to me.....
