Yeah.

Spoiler for Example:

In vol 2 when he got cornered, he activated his "light" by his own will. However as activating his "light" happened, it became the trigger to activating his second "side", namely the monster who thirsts for destruction. Still even when he is in that monster state, he retained his memories of what happened during the progress. He sometimes wonder why he couldn't stop his body even though he still kept his consciousness.
