The initiation at the magic school uses a measurement of your abilities presenting a status table. With Slayer I got
Output: Excellent
Refinement: Coarse
Endurance: Extreme
Alignment: Contained Chaos

The different paths to initiate into are valued using a level system indicating their difficulty. Although the magic circle is safe, one must finish the task or fail the task. Applicants are only accepted for tests they are estimated to have the ability to finish, but sometimes a person will use up all their life force because they do not use their energy effectively.

When I re-registered as myself, I got the same stats as Slayer, but 
Alignment: Bound Chaos

This is a less directional form of chaos which is simply "bound within the body", while Contained Chaos is bound to the spine, so Slayer is narrower.

To learn Chaotic Black magic, one needs to have
Alignment: Unbound Chaos

which is external to the body. Otherwise the energy output will be too low no matter what one does. Chaotic Black magic is graded at level 6. 
Ritual Black magic: lv4, Herbal magic: lv0.5, Ritual Love magic: lv1

Lower numbers means easier to initiate.

There is a way to force an alignment against your natural state, so I did this to get a double initiation standard and register again. My stats for Alignment: Unbound Chaos
were
Output: Mediocre
Refinement: Coarse
Endurance: Insane
where the "insane" quality means "completely chaotic, anything is possible" so that is a redeeming quality here.

I was able to finish the initiation for Chaotic Black magic. With this came the offer to get ritual items imbued with the magic I had just initiated into. I chose boots, a cloak and a short wand. These are provided to maintain a style expected of lv6 initiates, simply fashion to indicate your skill level.

When I left the school, someone on the street approached me and offered to sell me a house. I went with them to look at houses in the city and settled for one. I also ordered furniture and set up a ritual practice area. 

I have yet to see what comes of this, but I have already made use of the workshop to produce certain magic for effecting the world around me.
