When Hibiki asks Machio about the tournament, he reveals that it's for gym members only. He suggests that they all should enter. Setting up a table, Machio explains the rules of arm wrestling. In the first match, against everyone's expectations, Hibiki easily defeats Ayaka. Akemi was about to challenge her next until Machio stepped up and challenged her instead. Despite obviously overpowering Hibiki with his strength, he notes that he had to get a little serious.

On the day of the tournament, Hibiki finds out that there are only two people competing in the women's division: herself and a Russian named Gina Boyd. Despite being one of the best Russian arm wrestlers for her class, the match ends with Hibiki easily defeating Gina.

Several days later, Gina transfers to Hibiki's school vowing to take revenge, which surprises Hibiki, Akemi and Ayaka. Later, Akemi asks Gina about what kind of training she did at the Moscow branch of Silverman Gym. Gina reveals that she mostly took Sambo classes and also that she did arm wrestling as a hobby. She is then asked if she does any strength training and Gina tells them that she does kipping. After school, Akemi asks Gina if she's going to the gym with them. She tells Akemi that she can't because she's meeting her host family. Later that night, Hibiki arrives at her home when she notices a pair of shoes. She soon realises that Gina is staying with her.

## Machio's Muscle Lessons

### How to Arm Wrestle

* Grip peg with non dominant hand.
* Keep shoulders parallel.
* Elbow centered with body.
* Stomach touches table.
* Dominant leg forward.

This is proper form and lets you use all of your body’s strength more efficiently!

## Gina's Lessons

### Arm Wrestling Techniques

Hook Roll
You hook your wrist around the opponent’s and cover it from above. It’s a technique most suited for players who use brute force.

Top Roll
By yanking the opponent’s thumb, you drag their body towards you, throwing them off balance. It makes it harder for them to stabilise and easier for you to win, even if you’re weaker.

* Hoshina Eimi's motorcycle, a chopper, is a popular custom-style with "hardcore" types known for their radical size and extremely loud engine roar, common among most choppers.
	+ Given the loud roar of the engine, Eimi's chopper is certainly over 50cc and more likely over 400cc displacement (as is common with the Harley-Davidson twin-cam or the Honda's 750cc 4-cylinder), which means she certainly has an "ordinary" (普通) motorcycle driving license, which permits 16-year-old drivers. But she could also have a "heavy" (大型) motorcycle driving license which requires her to be at least 18-years-old, which implies a variety of other unknown attributes about Eimi (such as illegal vehicle operation or being held back at least one year given her status as a 2nd year student).

At Koyo Girl's Academy, Tachibana Satomi tells her colleague that she is gaining weight, but her colleague doesn't notice. Her colleague gives Satomi an advert sheet of Silverman Gym and tells her to try it out. Satomi worries she might see students at the gym, but she is reassured by her colleague saying "no high school girl would ever go to a gym".

After school Hibiki and Akemi decide to go to the gym. In the locker room Satomi is shocked to see Hibiki and Akemi there as she would have never thought that they would get along. Because of the students, Satomi doesn't seem to be interested in joining the gym anymore until she meets Machio. Machio asks Satomi if she had done any exercise in the past and she replied that she had tried calisthenics but stopped due to the pain in the muscles that she had worked on. Machio then tells to focus on muscles that aren't in pain and that today they would do "dumbbell curls". Machio also explains that working out isn't about the weight you can lift but "efficiency with perfect form" (as it is common amongst men to ego lift). Akemi then notices Satomi has a diamond tan mark on her belly button and questions where she got it. They come to the conclusion it is from a weird swimsuit she wore. However, Machio inadvertently covers for her and they drop it.

After finishing at the gym and the girls head home, Satomi breathes a sigh of relief as it revealed the tan mark was from a costume and Satomi is a cosplayer.

Шестой ярус

Шестой ярус, по словам побывавших там, тяжело описать. Это огромных размеров мир под миром, освященный лазурными водорослями, свисающими со дна пятого яруса. Тут находятся древние города, которые построили задолго до нас. Их населяет что-то, что истребило предтечей. Люди, забредающие в пустые дома, всегда чувствуют сильное жжение в груди. Они охотно рассказывают о том, что находится в этих местах, порой рассказывая то, чего там фактически нет. Наверняка можно сказать лишь о том, что живущие тут монстры истребили предтечей...ведь так?

## Summary

In the teacher's lounge, Aina and Kure-sensei ask Satomi if she's going to hang with them tonight. Satomi tells them that she can't because she has something to do. After she leaves, they wonder why she's been so busy lately until Aina sees her Silverman Gym card. They then head to the gym where they meet Satomi and their students. Machio introduces himself to them and instructs everyone to try the side bend. Afterwards, Aina and Kure-sensei head home.

In November, the second year students of Koyo Girl's Academy are on a field trip where they're hiking up a mountain. During the hike, Kure-sensei explains the proper technique and exercise for hiking, which motivates Hibiki, Akemi, Ayaka, Satomi and Aina. However, Hibiki, Satomi and Aina end up falling behind the group and taking the wrong trail. At the summit, Ayaka notices that they're missing. On the other side of the mountain, Hibiki, Satomi and Aina freak out when they realise that they're lost. Once they calm down, Satomi notices a tree and explains how to do tree and rope climbing. As they're climbing the tree, Kure-sensei realises that they went to the athletic corner of the mountain. Meanwhile, a mysterious man tells his secretary to book a trip to Japan.

### How to do Side Bends

* Stand upright with a dumbbell in one hand.
* Bend towards the side you’re holding the dumbbell with (low-intensity variation) or away from the side with the dumbbell (high-intensity variation).
* Focus on flexing the obliques to pull yourself back upright.
* Make sure you’re balanced properly and not swinging.

## Kure-sensei's Lessons

### Efficient Hiking

* Walk straight and tall. This ensures proper posture – shoulders rolled back, chest out, spine neutral, eyes forward.
* Keep your knees bent at all times. On uneven surfaces, this lets your knees absorb the shock on each step.
* Step with the whole foot. Correct walking posture is landing on the balls of the foot, so I’m not sure why this advice was given.
* Take short steps. For uneven surfaces, smaller steps give you more control and keep you balanced.
* Maintain a steady pace. It’s not a sprint, and you can never be sure of what’s on the trail. Keep a good walking pace to conserve your energy whilst not disturbing the surroundings.
Жизнь в городах

Жизнь в городах стала набирать популярность много веков назад. Сейчас трудно представить другие варианты, ведь деревни давно перестали быть безопасными, лишь фермы могут позволять себе сельский образ жизни, поскольку имеют хорошую защиту от голодных лесов или удобное расположение. Население городов зависит от географии, но, как правило, большей частью оно коренное. Это связано с тем, что транспорт сделал резкий скачок в развитии только пол века назад, в **1874** году, после изобретения модели поезда *Марк 2* русским инженером Пироцким Фёдором Аполлоновичем. До этого поезда были менее безопасными, а потому подвержены опасностям лесов, если маршрут пролегал через них. Иммигрантам приходится туго, ведь они в новых краях чужие. Даже между городами одной страны укрепляются местные законы, обычаи и диалекты, из-за чего два человека одной культуры, проживающие в разных городах, могут находить друг в друге бытовые странности. Как правило, иммигранты являются тружениками низших рабочих сфер из-за недостатка образования или сегрегации. Только у самых квалифицированных специалистов из других стран получается взять от жизни должное.

В прочем, и у тех, для кого дом является родным, все не так гладко. Примерно половина населения являются рабочими низшей квалификации, которые обслуживают заводы. Все чаще рабочие устанавливают себе дешевые протезы, лишая себя старых конечностей в пользу новых, не знающих усталости. Такие рабочие получают больше денег за счет более эффективного труда, но дешевизна протезов приводит к тому, что люди испытывают фантомные боли, которые глушатся наркотиками.

Для коренного населения, которое окружило себя печатными машинками, почтовыми пневмотрубами, бумагами и ручками мир куда радужнее. Они посещают кинотеатры и кафетерии, покупают машины и поселяются в более престижные районы, чем наполненные "муравейниками" улочки. В таких районах куда меньше шансов быть ограбленным или убитым, ведь полиция бдит для благополучия граждан. При любом преступлении можно позвонить по домашнему телефону или в телефонной будке оператору 911. Он немедленно передаст ваш запрос офицерам полиции.

В самых богатых районах живут элиты. Они используют лучшие машины на тайоновых двигателях, они посещают лучшие рестораны, они просматривают фильмы на домашних проекторах и пьют лучшие вина. Некоторые из них пытаются избежать старости с помощью переноса мозга в тело автоматона. Только таким людям доступны столь дорогие операции.
