Penguin Musume♥Heart

A girl who introduces herself to people as "Penguin" and who loves animation, has transferred to Hokkyoku High School. Her real name is Sakura Nankyoku.

While Sakura is pressing Kujira to wear a costume from her favorite animation "Takenoko-chan," a pretty intruder appears.

While Sakura is attending the regular meeting of the Hokkyoku Student Council, Kaede, her younger sister, comes to bring a forgotten item.

Kaede arrives at the Hokkyoku-cho Fireworks Show, in the company of the regular members, all dressed in yukata.

A mysterious beauty by the name of Mary Chupacabra W. Whitebear sends a challenge to Sakura Nankyoku!

Sha Chi tries to attack Sakura, who as always clings to her favorite friend, Kujira.

Nene performs one miracle after another in front of Sakura and Kujira.... It turns out that Nene Kurio is a shrine maiden.

The sinister reach of Whitebear Corporation led by Mary Chupacabra W. Whitebear extends to Sakura. A well-prepared and heinous trick threatens the closure of Hokkyoku High School.

Everyone at Hokkyoku High School are captured as hostages. Sakura and her group become lost in the labyrinth of Shirokuma Gakuin High School while the Four Heavenly Kings attack them one by one.

In all honesty, characters with names like the "Four Heavenly Kings" are two-bit villains destined to be defeated.

Do you hear it? Surely you do! The prayer should reach you! The battle ring appears in front of the students of Hokkyoku High School and Shirokuma Gakuen!

Hokkyoku-cho is in ruins. After a while, the streets show signs of recovery with the help of Nankyoku Corporation.

Shirokuma Gakuin was acquired by Hokkyoku High School. Mary and the Four Heavenly Kings are also enrolled there.

Sakura, responding to the "moe" factor, locks on to a sweet junior student!

Kujira flashes back to the embarrassing experience of declaring her love for Sakura six years ago.

Kujira's time travel begins to warp history! Flustered, Kujira goes back to the past and desperately works together with her younger self to change the distorted future back.

Assassins are silently approaching the poor Mary! The Whitebear Four Heavenly Kings are defeated by Riff and Aqua, agents of an unknown enemy, and Mary is kidnapped.

The Four Heavenly Kings and Sakura's group go to save Mary, although Kujira desperately tries to stop them.

Sha and Nene square off against Aqua from "Kuro-bara Communications." Cooperating, the two manage to defeat Aqua, but have spent all their energy during the intense battle.

Sakura enters a church to rescue Mary and finds a disturbing scene; numerous photos of her cover the walls.

Sakura fights Mariana on top of the Tower of Thorns! But the overwhelming strength of Mariana forces her into a pinch.

Surprisingly, Mariana turns out to be Sakura's mother. The numerous trials and adventures had all been given to Sakura as a kind of surprise exam to confirm her growth and development.
