Kokoro Tsurumaki(Japanese:
BandHello, Happy World!The vocalist, and also one of the HHW Three Idiots, she is the only daughter of a very wealthy family and will do whatever it takes to realize any "I want to do it" idea that comes to mind. Full of curiosity, her eyes are always shining with the light of wonder. She loves seeing people's smiles. AttendsHanasakigawa Girls' Academy。
She likes all kinds of food! There's no food she dislikes! She loves looking for happy things everywhere and is not good at dealing with negative people., even her childhood friend Charlotte。
She is also Hello, Happy World!'s
Her athletic nerves are top-notch. She can do backflips on stage at will, and sometimes even enters from the audience seats at the start, then "swims" to the stage via the crowd surf.[3]She raced against Kaoru and Hagumi and won first place(it seems Kokoro had a false start). Misaki once chased Kokoro for a whole day without catching up. Jumping directly from a third-floor classroom window is a piece of cake for her. She's also good at beach volleyball, forming a team with Hagumi that defeated Eve and Tae's team[4](you two basically stomped them)。
Although she, Hagumi Kitazawa, and Kaoru Seta are called the "Three Idiots" by fellow band member Misaki Okusawa, she actually learns everything very quickly. In a mini-map conversation, she picked up Kanon's drumsticks and played the drums skillfully; while learning Wadaiko with Kasumi and Misaki from Tomoe, she figured out the most correct drumming posture on her own and performed high-difficulty moves that even advanced Wadaiko players find challenging[5]; in a loading screen comic, she learned horse riding without needing Kaoru's instruction; she performed well on her first attempt at juggling; she has very unique insights into the band members and has seen through to the inner side of each member.[6](Misaki commented on her as "Surprisingly quick at learning everything, a genius, but it's a pity her talent is wasted.")
She has bright long straight blonde hair that is very conspicuous in a crowd. The shape of her hair strands looks a bit like french fries.Hikawa sisters magnet (just kidding)
In the game, when Kokoro has unusual ideas or becomes interested in something, her eyes shine brighter than usual. (Among the 35 characters, others with the same setting includeKasumiandHina, and in the anime,Taealso has this setting, truly on the same wavelength.) In the April Fools' Easter egg, Kokoro's Michelle mask features three four-pointed stars in the eyes.

Among the eight vocalists and the five members of HHW, she is
Kokoro's usual strange behavior makes others reluctant to approach her; she is known as "Hanasakigawa's Alternate Dimension" at school. Before HHW was formed, she didn't have many friends, and her Astronomy Club, like Haneoka's, only had one member.But in reality, Hanasakigawa doesn't have an Astronomy Club. When Kokoro was caught stargazing on the school rooftop at night by a patrolling teacher, the teacher, fearing the Tsurumaki family's financial power, could only rationalize Kokoro's actions by "establishing an Astronomy Club." This is completely different from the one who joined the Astronomy Club but ended up as the only member because no one could understand her,Hinawhich is completely different.[8]Even so, she has a very happy life at school.
The reason she seems to never have any worries is that Kokoro can see through everything. Because of this, she cannot understand what the feeling of worrying is, which in turn causes her to worry. (Kokoro: Is this tight feeling in my chest what "worrying" is?)[9]
In the early stories of the mobile game, when Kokoro is troubled, she tries her best to think of happy things and forget the person who caused her worry. So far, the only person who can make Kokoro feel troubled and stop running away from that feeling isthis one person。
Although she usually gives the impression of a rocket constantly charging forwardThis also led to Charlotte's loneliness from over-imitating Kokoro, which in turn created a desire for revenge against Kokoro. In fact, her home stores many items filled with memories, so she might be a very nostalgic person[10]。
She usually likes reading picture books, and her favorite is "Kuma to Kuma" (Bear and Bear).
Officially set as a DD, yet currently, the production of fan-made CP content related to Kokoro is dominated by a single pairing.Kasumi, you should learn from her
The ultimate rhythm master in Bandori; of the 35 characters in the game, those who have beenswept up in Kokoro's pacealready account for more than half, and even the orthodox band'sRoseliapractice fanaticSayois not exempt.
One of the "Only you in the whole world don't know Misaki is Michelle" trioHowever, both the anime and the game have hinted or explicitly stated countless times that Kokoro knows Misaki is Michelle., it is speculated that among the "Three Idiots," onlyHagumireally doesn't knowMisakiis Michelle; whether she's playing dumb remains to be seen until the official story fills in the gaps.
The surname "Tsurumaki" comes from Tsurumaki, Setagaya City, Tokyo.

The Tsurumaki family's wealth is beyond normal limits (netizens speculate it's comparable to Middle Eastern royalty or top US arms dealers), often referred to as "money power." Even others who possess "money power," such asRinko Shirokane、Kaoru Seta、CHU²etc., cannot compare to her inhuman level of wealth.
Because of Kokoro's family background, she can basically obtain anything she wants easily. She has her own
Building a Michelle Land is no problem at all. Kokoro once asked everyone where they wanted to go for fun, and after Misaki discovered she had drawn blueprints for Michelle Land based on everyone's ideas, she was so scared that she immediately grabbed her hand to stop her.[11]。In the end, one was actually built.[12]
Additionally, she has the naming rights to a star and wants to takeRanandTsugumi,fly there. (It sounds nonsensical, but given the Tsurumaki family's financial power, Kokoro might actually be able to take them to space.)[13]
Although Kokoro's family wealth makes one involuntarily exclaim "The terrifying Tsurumaki family...", Kokoro doesn't actually rely too much on her family's resources; she still earnestly does things that are only meaningful if done personally.

How many do you want me to shoulder?"

[The following is an excerpt from Kokoro Tsurumaki's 3-star basic card story "The Person in the Suit is a Worrywart"] |
Kokoro views Michelle and Misaki as separate people, and often forgets Misaki in the band's main story. Some players speculate that Kokoro frequently and intentionally makes Misaki become Michelle in order to "bring a smile" to Misaki, who is often gloomy and complains about everything, because Kokoro knows that she will at least smile when she is Michelle.
The reason for intentionally forgetting Misaki is mentioned in her initial 3-star card, but after Misaki expressed how much she values HHW, the gag of forgetting Misaki was never used again[18], and she even says "No matter where I go, I'm happy as long as I'm with Misaki!" in the Hanasakigawa Girls' Academy area on the map.
In HHW Band Story Chapter 1, Episode 20, Misaki'sheartfelt confession"...I get it, fine. Maybe one day you'll get tired of it, but until then, I'll play along with this fairy tale of yours to the very end." which eventually led toMisaKokopairing.One of the official major ships。
Kokoro mentioned that she can have happy dreams when surrounded by her favorite things while sleeping (currently confirmed "favorite things" include a pair of Wadaiko drumsticks, a Michelle support fan, 3 large Michelle body pillows, and a jack-o'-lantern; the rest are unknown)[19], almost all of which are items related to Misaki.
During Halloween, Kokoro stated when Michelle appeared, "While I'm happy Michelle is here, I really wanted to wear witch outfits with Misaki."[20]Thus, in the new dialogue added to the map for Halloween 2018, Misaki wore a Halloween costume in her normal state. Just how much do you spoil Kokoro?
Kokoro once invited Misaki out alone during New Year's and mentioned that she dreamed of Misaki in her first dream of the year.[21]Kokoro told Kaoru about this in a map conversation, and Kokoro even forgot what she said to Misaki in the dream.
In the Band Story Chapter 2, it's also evident that both Kokoro and Misaki pay attention to each other (Misaki remembers that Kokoro is the worst at dealing with negative people, while Kokoro remembers things Misaki said to others a long time ago).Although they argue fiercely, they always make up by the end of the day.
At the CiRCLE New Year's party, she performed ball juggling with Misaki and even improvised riding a unicycle to increase the difficulty.[22]
In the second season of the anime, to prevent Kokoro—who jumped off a high platform on a whim—from falling into the sea, Misaki forced herself to overcome her fear and learned how to operate Michelle's Happy Flight Mode, andprincess carryingKokoro took her through the fireworks and safely returned her to the Smile Ship.Michelle: A bear that can't fly is just an ordinary bear!The wife-protecting bear makes her entrance.If this isn't love
In the 2019 Kokoro birthday member congratulatory voices, Misaki sets aside her tsundere awkwardness and takes the initiative to invite Kokoro to celebrate at Smile Park.
andKasumi ToyamaThey get along very wellAfter all, they are on the same wavelength, the two of them mix the slogans of their two bands in their live interactions in the mobile game. "popipa, pipopa, smile, yeah!!!” “happy, lucky, popipapapipopa!!!”
With fellowsolemember of the Astronomy Club, the two have a very good relationship and even discussed going to look for stars together. (Then they ended up at one of the Tsurumaki family's mountain villas.) When Hina Hikawa's Astronomy Club faced the crisis of being disbanded, Kokoro heard the news from Hina's sister Sayo, and before Sayo could even react, she dashed off to Haneoka to reach an agreement with Hina. Afterwards, the inter-school collaborative stargazing event was a complete success, and the crisis for Hina's Astronomy Club was resolved.
andRoselia'sRinko ShirokaneThey have a good relationship; Rinko once said that holding Kokoro's hand is very reassuring, and on Kokoro's birthday, Rinko gave her a picture book as a birthday gift.
With Pastel*Palettes'Eve Wakamiyashe is also on good terms, and the two once split watermelons together on the beach.Eve might be more interested in a certain katana at Kokoro's house than in Kokoro herself.
