Description
In the anime Kirarin Revolution, Baba-chan is the affectionate name for the maternal grandmother of the main protagonist, Kirari Tsukishima, and her brother Subaru. The name itself is a familiar Japanese term for grandmother. While she appears as a recurring character in the anime series, her real name is never revealed.

Baba-chan presents the exterior of a gentle, kind, and wise older woman who is always there to support her family. She is a reassuring presence in Kirari’s life, often offering a calm perspective. However, this calm exterior hides a surprisingly spirited and comedic secret. Despite her age and her role as a grandmother, she is a devoted secret fan of the popular idol group SHIPS, with a particular and intense crush on the member Hiroto Kazama.

This secret fandom is a core part of her personality and her primary motivation for much of her quirky behavior. She goes to great lengths to hide her enthusiasm, pretending to be ignorant of the entire idol world when talking with Kirari. For instance, when Kirari mentions idols, Baba-chan will innocently ask what they are. Behind the scenes, however, she keeps a hidden poster of Hiroto, and whenever she daydreams about him in a romantic way, Hiroto himself can inexplicably feel a chill run down his spine. Her stated reason for this affection, that Hiroto reminds her of her late husband, is quickly proven false when a photo of her husband looks nothing like him.

In the story, Baba-chan serves as a source of quiet encouragement and comic relief. She is a pillar of support for Kirari, cheering her on as she pursues her dream of becoming an idol. Her role is often that of a doting grandmother who provides a home-cooked meal and a place of comfort. Yet, she also inadvertently serves as a connection to Kirari’s inherited traits. In a humorous twist, it is suggested that Baba-chan is the source of Kirari’s original tone-deafness, passing down this less-than-desirable genetic trait to her granddaughter. This detail highlights her role in Kirari's journey, as Kirari must work hard to overcome this natural disadvantage.

Her key relationships are primarily with her family. With her granddaughter Kirari, she has a loving bond built on mutual care, even as she keeps her fangirl tendencies a secret. Her secret obsession creates a one-sided and comedic dynamic with Hiroto Kazama, whom she idolizes from afar without him or her family initially knowing the full extent of it.

Throughout the series, Baba-chan does not undergo a dramatic personal transformation. Her development is more about the gradual, often humorous, revelation of her hidden depths to the audience and, occasionally, to her family. Her secret is a running gag that adds a layer of warmth and laughter to the show. Her notable abilities lie not in singing or dancing, but in her capacity for unconditional support and her masterful skill at maintaining a double life as a simple grandmother and a secret, devoted idol fan, all while keeping her eyes perpetually closed in a serene smile.
