School Rumble Chapter #1


School Rumble Episode #1


School Rumble: Third Semester Episode #1

Yakumo Tsukamoto (塚本 八雲, Tsukamoto Yakumo) is the younger sister of Tenma Tsukamoto. At first she was presented as a supporting character, but her relationship with Kenji Harima had become one of the central focus of the School Rumble which promote her as one of the main characters of the series (same as Eri Sawachika).



Mysterious and soft spoken, Tsukamoto Yakumo (also referred to by Kenji Harima as Imouto-san) carries a strong presence with her wherever she goes. She can hear the thoughts of people who have strong feelings for her and is a member of the Tea Club. She has a tendency to fall asleep anywhere and is afraid of dogs. She also works at Cafe Mercado.

Yakumo makes her debut appearance in chapter #1 of the manga (Episode #1 in the anime). Her picture appears on the cover of Volume 2. She is also the featured character of the second image album.


Yakumo's character traits are identifiable with the typical female roles played throughout Asian society, a caring woman with strong family ties. Traditionally, Asian women are supportive, but dependent on the individuals they are close to. Thus, in Yakumo's case, her dependency would be Tenma. Yakumo has a strong personal duty to house work, cleaning, and is very diligent and well-mannered. She accepts the social position of caretaker and executes her responsibilities without complaints. She does not have a personal agenda or goals and her sole desire is to serve her family.

This persona relates her closely to the generic female role in Asia but also crosses her over into another classification "the Housewife", or Yamato Nadeshiko, which is commonly found in male audience oriented anime. On top of her house duties, Yakumo's demure and shy nature blends with her acute mannerism to portray the perfect wife candidate. This character trait is further emphasized by Yakumo's ability to exceed in almost everything, such as; sports, schoolwork, and games. She is well knowledgeable and elegant yet has a high tolerance. She is never overtly angry nor does she show signs of frustration.

Psychic Ability

An instance of Yakumo's psychic ability.

Yakumo has an ability to hear the thoughts of people who have an interest in her. This happens often throughout the story, creating awkward moments for her. Her psychic ability is a slight deterrent as it keeps her from developing feelings for most guys. However, one character that does intrigue Yakumo is Kenji Harima. His infatuation with Yakumo's older sister Tenma, keeps Harima's thoughts shrouded from Yakumo. These circumstances contribute to the development of a somewhat normal relationship between Harima and Yakumo (However, Yakumo does develope romantic feelings for Harima). Because of her Tenma's sisterly love for her, Yakumo is also privy to her thoughts.


Yakumo works at a local Cafe in Yagami called Cafe Mercado. There she is a waitress serving customers and assisting them like a normal restaurant waitress. Cafe Mercado's dress code encourages different outfits for seasonal occasions.


Yakumo has multiple talents. She is capable of reading minds as well as drawing manga. Yakumo appears to succeed in everything she does.


Her cooking ability is far above par. You see Yakumo's cooking in several occasions throughout the series. The other characters always comment on her exceptional culinary skills. A few memorable instances are when she makes Onigiri for Harima when he comes to her house to fix her AC. Another instance is when Tenma has a sleep over and Yakumo serves the girls dessert. Another one is when she cooked fish for that stray black cat. (Iori)


Yakumo takes manga editing lessons from Mitsui, the Chief Editor. She also assists Harima with his Manga, doing the inking work.


Yakumo is talented and well trained when it comes to sewing. One occasion where you see an instance of this is in Episode 24. Previously Eri had made repairs on a jacket of Harima's. Without knowing, Yakumo sees the poor stitch work and repairs it herself with an exceptional result.



Tenma Tsukamoto

Yakumo is Tenma's younger sister. However, their roles are often reversed with Yakumo being the primary caretaker of Tenma; she is also sometimes mistaken as an older sibling of Tenma, due to the latter being shorter and possessing a more childish personality. Yakumo has a very close relationship with Tenma and is very protective. One example would be Episode 8 when Tenma is attempting to cook a curry dish for Karasuma. Although Tenma remains reluctant and refuses Yakumo's help, Yakumo continually comes by to check on her. Then Tenma accidentally lights the stove on fire and Yakumo comes to extinguish her engulfed curry. This metaphorical example illustrates the kind of protective relationship Yakumo and her sister can have. Contrary to Yakumo's usual role with her sister, Tenma has acted in a protective manner about Yakumo. In Episode 16 during the camping trip, Yakumo becomes increasingly friendly with Harima. Due to certain situations in previous episodes, Tenma has a poor opinion of Harima and warns Yakumo to stay away from him.


Kenji Harima

Yakumo and Harima

Yakumo and Harima

The only male whose mind she cannot read, Harima helps Yakumo to discover an interest in manga, an interest that she later pursues by taking manga editing lessons. Harima considers Yakumo his closest friend, and Yakumo clearly cares deeply for him, going way out of her way to help him out. Eventually, Yakumo falls in love with Harima, but refuses to have a relationship with him because of Harima's love for her older sister, Tenma. It remains unknown whether Harima felt the same way about Yakumo, but it is unlikely due to him still being in love with Tenma.

Shuuji Harima

Yakumo takes Shuuji into the Tsukomoto home for a brief period to get him out of the rain, and Shuuji has a deep admiration for her.

Sarah Adiemus

Yakumo is rather self-kept when it comes to socialization with other characters although unbeknownst to her, she is very popular in school. By far her closest friend is Sarah Adiemus, a fellow Class 1-D student. Sarah introduces Yakumo into the Tea Club which Sarah is a member of. The background behind the beginning of their friendship isn't introduced until the 1st OVA episode. During this episode, Yakumo is chasing after her cat Iori when suddenly a fierce dog appears. Yakumo, not being comfortable with dogs, becomes scared. Sarah then appears and scares the dog away saving Yakumo. This forms a relationship between the girls and they quickly become best friends.

Eri Sawachika, Mikoto Suou , and Akira Takano

As Yakumo is very close to her sister and goes on trips and other activities with her, Tenma's three best friends are fairly close to Yakumo as well. Akira and Yakumo work together on Tea Club activities as well.


Eri Sawachika

Due to the frequent misunderstandings that Yakumo was going out with Harima, Eri and Yakumo have a slight rivalry that has manifested itself most notably during the school Cultural Festival play.



Although Yakumo's relationships with other humans are often hesitant, she always seems to have an interest in animals. Early on in the series, Yakumo is seen making an extra bento box. We later find out that Yakumo has prepared a meal for a stray cat at the local Yagami Shrine. The relationship that Yakumo has with Iori starts out gradually. Iori acts timid around people and at first, Yakumo is no exception. Further into the story, their relationship begins to build. Iori eventually becomes the Tsukamoto's house pet and makes random appearances in a few different episodes.

Love Interests

Kenji Harima

Yakumo has never been on date with Harima, but she has feelings for him throughout the later episodes of the anime and within the manga also. Yakumo fell in love with Harima after spending more time with him (helping him with his manga). Eri, however, was angry to figure out that Yakumo liked Harima just like her, and tried to make sure Harima didn't end up with her. Yakumo admits her feelings to Harima, but Eri wouldn't accept it, and tried to get between the two.
