<p>Shape corrosion is the term used in Black Bullet to define how much of the host body the Gastrea virus has taken hold. If it gets over 50%, the human turns into a Gastrea monster.</p>

<p>It is specially important for the Initiators, because they are infected at birth, and there is always a risk they turn into Gastrea in the middle of an operation. If an initiator is injected with more virus (by monsters, for example), shape corrosion can increase in a very short time.</p>

<p>During the series we learn that</p>

<blockquote class="spoiler">
  <p> Aijara Enju's Shape Corrosion is well over 40%, putting her almost on the death row, should the virus spread more.</p>
</blockquote>

<p>There is special medicine all initiators have to take regularly to halt the spread of shape corrosion, but is there any method mentioned in the black bullet manga or anime of reverting this index?</p>

Can shape corrosion of an Initiator's body be reversed, or only contained?
