A girl who doesn't put on appearances. Not worrying about how others see her, she’s calm and goes at her own pace. She actually has an eccentric, creative, loud, and cheerful side.

It would be a mistake to think that Maru is cold unfriendly or uptight. As long as she connects with people who can match her frequency, she can give so many surprises, light up, and leap from one thought to another. But sometimes she can be so forthright that it sounds too cold or harsh for some people. Few things energize her like the opportunity to swap ideas or enjoy a lively debate with another curious, inquiring soul.

Maru is a smart and talented girl. This is also supported by her family environment as her privilege, most of whom work in the educational field, from her mother’s side, Hidaka. She is the type to think for a long time. But it also becomes a double-edged sword that made it difficult for her to immediately make a decision.

Her greatest fear is making the wrong decisions, putting her family or her loved one in danger, and blaming her wrongdoings on herself. It makes her easily stressed and triggers nosebleeds which is a hereditary disease in her family lineage.

Maru isn't necessarily dishonest. She has trouble speaking her mind about how she truly feels and tends to bottle up her feelings. She doesn't like expressing strong feelings or showing her true self. Therefore, it's hard to tell what she's thinking.

Once a time due to her trauma caused by bullying and ‘betrayal’, her loyalty became only to herself, and those who aid her currently, and would not go out of her way to help another unless she needed that individual's help in the future. She had an acute trust issue and harsh judgment, being alert most of the time. It made her become very isolated and prefers to work alone without consulting anyone. This is also exacerbated by family prolonged conflicts on her late father’s side.

Even when she followed Leo and Izumi to Yumenosaki as a transfer student after what happened in Checkmate, her main intention wasn't purely to help Leo. She looked at her reflection in that person, wondering if he could survive. Whether she needed to intervene so that she too could figure out a way to 'save' herself.

She believed that being soft-hearted would only make her easily deceived and crushed by others. However, over time and what happened after entering Yumenosaki and making genuine relationships, she finally opened up little by little again, and slowly ‘regained’ her sense of sincerity.

Maru decides to do what she herself wants to do, not what others expect her to do. She allows herself to embrace friendship and discard solitude, and show her desire to live on.
