Dolphi is shown to be a very timid and innocent person who's afraid of many things, especially sharks. However, in a fight, she is quite brave and willing to protect Wadanohara from enemies. Having the highest damage output, it could be implied that she is very physically strong.

Dolphi also tends to be fairly naive and impressionable. She tends to go along with whatever Memoca says, and is very quick to take a person's word as truth. As shown when Memoca talks about "shooting rainbows". Despite Lobco vocally correcting Memoca, Dolphi continues to eagerly wait for these "shooting rainbows".
