She is also very trusting of and never doubts other people. However, when driven pushed her limits, Kurumi becomes scary and hunts down anyone who threaten her family. She loves her family a great deal.

As mentioned by her mother and her son, she is unable to keep secrets. This was seen when she has occasional slip ups of Kusuo's abilities and sheepishly tries to cover up, forcing Kusuo to have alter memories of those who heard it. She would apologize because of her excitement of discussing her son.
