Sailing 13 - New Members

Yayoi and the new yacht club members

At the start of Marika's second year, Yayoi was one of the four new members that joined the yacht club. She nervously introduced herself to the others before going off to the simulators with the second-years [2].

While Marika was contacting Show in the clubroom, Yayoi and the other first-year students were taking part in a simulator exercise. She was present when the yacht club learned that the Bentenmaru crew was in quarantine and happily agreed to help Marika [3].

Yayoi was present on the bridge when the Odette II left the relay station for the 'practice cruise', listening as Lynn reminded everyone to stay sharp during the extra pirating duties they were to perform and that Marika would be overseeing everything as the Bentenmaru's captain.

After going over the plan (and discovering the stowaway princesses), the yacht club prepared to depart. Once they had finished their preparations, the yacht club left the Odette II and proceeded to head to the Bentenmaru. As they left, Yayoi and the other first-years looked back at the Sea of the Morning Star and the Odette II, commenting on how that was what their ship looked like from outside.

Once they were aboard the Bentenmaru, the yacht club gathered on the bridge. Though not knowing the exact launch procedure, the yacht club attempted to get the Bentenmaru underway, with Yayoi assisting Chiaki at the engine console, though the first attempt was unsuccessful. While they were wondering what to do next, Gruier brought out some snacks for everyone to eat while they thought things over, to everyone's delight. While they were enjoying the snacks, Marika was contacted by Show who gave them the ship's instruction manual.

With the manual in hand, Yayoi soon understood how the engine worked. The yacht club then carried out a second launch attempt, this time successfully. Marika then decided to try an FTL jump, but there was nothing regarding them in the manual. They were then alerted to the imminent arrival of several military ships investigating the earlier laser discharge. When Lilly asked if they could shake them off, Yayoi replied that they had launched at low propulsion so the propellant wasn't stable enough. With the ships approaching, Marika decided to attempt a jump, utilising the basic procedure she could recall. Considering the converter reactors, Yayoi recommended that they only use the more reliable alpha-reactor for the jump. With little time to spare, the Bentenmaru successfully performed the FTL jump, to everyone's relief [4].

After dinner, Yayoi settled down for the night, sharing a cabin with Gruier, Grunhilde and Sasha. The next day, she was present on the bridge as Marika came in after oversleeping. After changing into her captain's uniform, Marika briefed the group on the details of their pirate job, a raid on the Princess Apricot. Though quite a few had some doubts over whether they would be able to pull it off, Marika reassured them and restored their determination. After Marika thanked them, the group moved to carry out their work.

Yayoi participated in the raid on the Princess Apricot with the rest of the yacht club, dressed as a cowgirl [1].

Not long after celebrating their successful job, Yayoi and the others learnt about Jenny's situation and quickly agreed to help rescue her. However before they could act, they were alerted to an approaching craft, which turned out to be Jenny herself flying a Silent Whisper. After Jenny was brought onboard and had an intimate reunion with Lynn, Yayoi and the others observed the discussion with Show regarding the details of their new job. With the arrival of the Hugh and Dolittle fleet shortly afterwards, she and the others took their places on the bridge and worked to get the Bentenmaru to safety [5].

Shortly after touching down after the FTL jump, the Bentenmaru was soon surrounded by the Hugh and Dolittle fleet. Yayoi and the others worked to ensure that the ship avoided the enemy's attacks while Marika and Jenny discussed their next course of action. As the enemy was closing in, Marika informed them that their next destination would be Junigh Coolph's private ship, the Glorious Coolph, and they worked to help make their escape successful.

On reaching the Glorious Coolph, Yayoi was part of the boarding party that boarded the ship, discovering the revolutionary rally being held there. When Robert Dolittle arrived, Yayoi and the others moved to protect Jenny before she and Marika exposed Robert's misdeeds. Afterwards, the group celebrated their second success with another party on the Bentenmaru, before returning home [6].

Nebula Cup Arc (Anime-Only)Edit

Not long after returning home, Yayoi and the rest of the yacht club travelled to the relay station during a weekend to carry out cleaning on the Odette II. A couple of days into the cleaning, she accompanied the rest of the club to the Bentenmaru to deliver Marika's lost ring [7].

She later participated in the yacht club's race to decide the three representatives who would participate in the Nebula Cup, though she didn't qualify [8]. On the day of the tournament, Yayoi and the rest of the yacht club travelled to Calmwind and observed the race from the orbital station [9].

Pirate Hunter Arc (Anime-Only)Edit

While Marika was preparing both a farewell cruise for the graduates and her next job (in light of the pirate hunting incidents), Yayoi and several others were taking part in dinghy simulations [10]. Yayoi was present on the Odette II, when the ship arrived at the site of the battle between the pirates and the Grand Cross, only to find that the battle was over. She and the other yacht members boarded the Parabellum to return to the Sea of the Morning Star while the graduates took over flying the ship, remarking to Ai that she wished they didn't have tests when they get back. She was also among the yacht club members who greeted Chiaki at New Okuhama Airport [11].

Abyss of HyperspaceEdit

During the spring break before the next year of school began, Yayoi helped with the yacht club's preparations for their recruitment drive [12][13].

The day after Marika brought Kanata to the Sea of the Morning Star, Yayoi and the rest of the yacht club gathered together at Lynn's request. Lynn informed them of a mass information theft that had happened across New Okuhama City [12]. They then watched as Lynn cooperated with the Bentenmaru crew in tracing the worm, eventually leading them to discover that it came from the security software provider. While the Bentenmaru tracked down the culprit, she and the rest of the yacht club helped Kanata solve the puzzle left behind by Kanata's father [12].

Afterwards, Yayoi and the rest of the yacht club began a decoy operation, spreading false information in order to cover for Marika and Kanata, and mislead the Yggdrasil Group. However after the two left on the Bentenmaru, they discovered a bug that had been placed on Odette-kun at the cleaners, rendering their efforts useless. Though Chiaki discouraged them from further action, Grunhilde's resolve moved them into convincing Chiaki to let them try to help Marika and Kanata [12].

Yayoi and the rest of the yacht club were present on the Odette II as it arrived at Hrbek Oda, with the Barbaroosa acting as an FTL booster. Under Chiaki's command, they engaged the Yggdrasil ships, allowing the Bentenmaru to go after the Advaseele. Later, they located and assisted with the recovery of the Advaseele from the depths of subspace after it had penetrated the X-Point [12].

Timeslip Arc (Novel-Only)Edit

Yayoi was onboard Odette II when it went back in time. She was in charge of the engines and one of the main members of the bridge who discussed various strategies along with Marika, Lynn, Jenny and Gruier [14].

Skills & AbilitiesEdit

As a member of the yacht club, Yayoi has knowledge of how to fly a dinghy from training simulations (though she hasn't flown one for real [8]) and experience at operating certain systems aboard the Odette II. She also has some knowledge of how to operate some systems aboard the Bentenmaru. Since her family owns a two-engine cruiser, Yayoi has experience in working with engines, which help her run the Bentenmaru's two converter reactors [1].


Hakuoh Academy Yacht ClubEdit

Yayoi is on good terms with the other yacht club members, all of whom are friends with one another, and will help them out when possible.
