Aim for the Ace!

Hiromi Oka, a first-year student at West High School, joins the tennis club admiring Reika Ryuzaki, aka Mrs. Butterfly, and senior Todo. She is a complete beginner, but as soon as she joins the club, the devilish coach, Munekata, sees her talent.

Hiromi Oka's been chosen to play on the top-class Nishi High tennis team. The older girls glare coldly... Even the kind and beautiful Madam Butterfly won't talk to her. Hiromi wants to quit the team, but Coach Munakata won't let her...

Regional preliminaries begin, and Hiromi is filled with dread. There to cheer her up is the kind Takayuki Todo. And Madam Butterfly gives her favorite racket to Hiromi.

In the middle of her match, Hiromi gets a leg cramp and falls to the ground. Kyoko Otowa, full of contempt for Hiromi, demands the coach let her play a practice match.

Hiromi is devastated by the loss of her racket. But Coach Munakata couldn't care less, as his brutal training continues. Good luck, Hiromi! You can do this!

At last, the semifinals have begun. Kita High takes the first set, 6-2. Calm down, Oka! Just stay calm! Munakata's scolding makes Hiromi move.

The Orchid's powerful serve flies like a bullet. Pelted down by those shots, Hiromi falls to the ground. I'm scared of the court! Hiromi cries out.

Otowa is very upset by Coach Munakata's handling of Ryuzaki's injury. The very next day, a special meeting is held, where Munakata and Hiromi find themselves targets of unbridled rage.

Before her individual match, Hiromi's pairing changes. Her opponent is none other than her idol: Madam Butterfly. Faced with Hiromi's unexpected potential, Reika gets serious.

Then, one day, Hiromi is summoned by Madam Butterfly and presented with a serious issue.

With Hiromi having returned to the tennis club, Kyoko Otowa resumes her bullying. Regardless, Coach Munakata's strict training continues.

Hiromi wins the tournament and is hailed throughout the school as the second most successful newcomer following Madame Butterfly. Munekata starts training Hiromi and her team hard for tomorrow's final.

At the celebration party for Nishi High's group win, Kyoko Otowa hands in her club resignation. Munakata is shocked, but her decision is firm.

Hiromi can't get along with Madam Butterfly, and their pairing isn't working out. Increasingly worried, Hiromi's playing only worsens. As if to reject her further, Madam Butterfly takes a day off from practice.

With their eyes set on the Kanto Tournament, Hiromi and Reika are training hard. However, Hiromi's misplays are rampant. But the invincible doubles pair of Todo and Ozaki are there to watch over her.

The first round of the Kanto Junior Doubles Championship series has begun. Reika and Hiromi face a tough opponent: Showa High. Reika continues to ignore her partner and play by herself.

Hiromi and Reika are backed against the wall after losing the first set. But Kihara and Izuka are relentless with their Tornado Serve. Finally, the second set hits a 5-5 deuce. Will Hiromi and Reika be able to break through the Tornado Serve?

Just running fast won't get you far in tennis. That's Coach Munakata's advice to a proud Hiromi as she runs around. But besides training more, there's nothing else she can do for now.

The doubles semifinals have begun. As Hiromi rushes to the court, a lone girl suddenly stands in her way: Her opponent, Yumi Kawamura of Ohara High.

With the Kanto Junior Championship finals match in sight, Hiromi's training kicks into high gear. And on the court, shining in the morning sun, Hiromi sees Todo training in silence.

Finally, the Kanto Ladies' doubles finals are here. Her heart swirls with anxiety and hope as Hiromi stands on the court. But at that very moment, as Reika is in the car, on the way to the match, an unexpected disaster unfolds.

One day, as Captain Hoshino's send-off match nears, Kyoko asks Coach Munakata if she can be paired with Hiromi. Then, she gives Hiromi a notebook filled with all of her shortcomings. Just what is Kyoko's intention?

The South Kanto Training Camp, which takes the top junior players, is taking place with 17 players, including Hiromi. All of the strongest players that Hiromi's faced so far.

Hiromi wins the practice match for the secondary member selection. But Munakata tells her that a match won without so much as an ace is no win at all and orders her to do even more training.
