I have not watched it full yet,but i skipped and saw three parts,one were he hypes about his song,another where he says that if kirikou did not participate in album its purely and simply because he is not on the spiritual level required to do it and proof with derangement were he was given chance and could not handle it,and he says if  an atalaku is not strong enough in the late night he can end up not waking up anymore in the morning because of the missions so that album succeeds and maybe one day he'll reach that level but they have to give chance to those who are strong both in normal and paranormal life hence why his animations were given to bercy
and also as usual he gave stick to fally

Marchouse,  In short he is saying Kirikou is out of the band again. It's really unfortunate,maybe Kirikou should concentrate on composing animation.

Is he serious about being spiritual just to be in album? And in his words what missions do they have to do?

What a silly bullshit, in Derangement kirikou was the best and the other atalaku seemed streetbands leaders, Bercy, Ruth Nzele and many others atslaku in Ferre section are ridiculous and us totally unfair to kick a talented guy like kirikou

Is he serious about being spiritual just to be in album? And in his words what missions do they have to do?

he is dead serious (but his big mouth nature will fool a lot of people to think he is joking),almost every of the big groups of drc including recent ones like team wata have a spiritual section who do the things for the group then individuals do things in hope to make a big impact but also to seduce the boss
i'll pick one stage example and a studio example
the stage example is bercy's test,aside from energy,bill likenss and all that,werra "felt" bercy  on spiritual level(the armband scene speaks a lot if you ask people who have bit of experience in those things)
the studio one,genta is my friend but i'll admit and i think i already said it that,he went  spiritual in bongolowayi/kipala nzonzako and result of it the generique started with some cursing words given to him which they never ever repeat in live and boom one of the most popular generiques ever,one of the rare generiques who can be played in a stadium with drums alone and atalakus and crowd singing
check carefully all the big groups you'll see that either the starting atalaku and sometimes the 2nd and 3rd are either in some very deep things,either kisi ya mboka mixed with a bit of christianism/islam and some rare cases like eclipse who are not into any of those
and even if animation does not always succeed,most leaders find it reassuring to have atalakus who are into those things,listen to the the nzinga generique of 13eme apotre starting with a prayer and nzinga announcing in previous albums in codes that he was getting into the game
 

Terrible! So without kindoki,these people can't make it now,right? This is terrible! If at this age of light, some people are still enshrined in values that dwell on and believe  in a lot of rituals and all sorts of diabolical practices for their albums or musical career to succeed or flourish...this is indeed terrible!

Wow, all that witchcraft stuff needs to stop. None of that is worth anything in the afterlife. How could they mix actual religions like Christianity and Islam with stananic stuff smh.
