After School, Satsuki was about to go back home together with Miharu and the Sendou Siblings when a magical circle suddenly appeared around her and threw her into another world.

Post-Summoning
After being summoned in another world, Satsuki is welcomed by the royal family probably François, Michel and Charlotte who explain to her she is a hero summoned by the will of the six wise gods. Secretly king François ordered his son Michel to gain Satsuki's heart. Soon after Satsuki requests her presence to be state-secret and a room for her personal use with forbiding anyone to enter without her permission. Not wanting to alienate their hero, François accepted. Being born in a prestigious and wealthy family, Satsuki is accustomed to people trying to use her, so she makes everything herself in her room (which is more like an appartement with kitchen and spare rooms) refusing servant. At first she is quite depressed as the standard living in Garlac is way below her living in Japan : the food is not good, use of bath is limited (as warming the water requires a lot of mana). She finds some comfort in the products of the Rikka guild which she remarks are very similar to Earth's products and begin to suspect something about Liselotte. After months of depression Satsuki decided to get a grip on herself and began to train with the knights to master her mysterious divine arm while rejecting Michel's courting but befriending Charlotte despite being quite sheming and cocky. Michel's failure leads king François to think of an another plan to tie Satsuki with Galark kingdom, he decides to do a great ball and inviting all the other heroes to allow Satsuki to meet with persons of her world and lifting her spirit and with that revealing her existence. Satsuki acceptes to be officially introduced as Galark's hero but on the condition that the kingdom searches a way to return in her world. At the end of volume 8 she is seen comtemplating the night sky from the balcony of her room, asking for herself if it looks like the sky in Earth. She is soon informed Liselotte arrived in the capital and has requested an audience with the royal family and her : a curious man pretends to have her friend in his custody and this friend wants to meet Satsuki who agrees immediately.

The next day, after learning the meeting has already started without her she barged in and focuses quickly on Miharu. Satsuki is extremely delight to see her best friend is safe and sound. As she discusses with Miharu she finds out François with a perplexed face and asks him what's going on. The king answer he can understand everything Satsuki say but Miharu's language is beyond his comprehension (the both of them spoke in japanese). Satsuki asks Miharu if she is also a hero but she isn't. François suggests Satsuki takes Miharu for a more intimate meeting as it is her long waited reunion, Satsuki agrees and leads Miharu to her room in the royal palace but not before greeting Rio and Liselotte and saying she would like also to speak with them. She finds Rio quite shaddy.

Once the two of in the room Satsuki asked what happened to her friend since their separation. Miharu tells her that soon after she found herself with Aki and Masato in a grassland. They were terrified when slavers capture them but Rio came and save them. They spend time with the gray-haired boy who helped them to get used to the Strahl regions by learning the common language and etc. Satsuki is deeply impressed because she had not the same problem as her divine arm could translate. Miharu reveals Rio is a reincarnated one and has the memories of a japanese, she also suspected Rio knew where to find them and has to tell lies to the king about an translation artifact for protecting Rio's secret. Satsuki began to understand why Miharu trusts the young man so much : he saved, protected and allow them to reunite with her, all of that without asking anything in return. Satsuki asks Miharu for Masato and Aki's whereabout while feeling ashamed to think Rio looked like shaddy, Miharu answered they are in a safe place as she does not know how Galark kingdom would treat them. Then Miharu asks about Satsuki's conditions and what will happen to them. The hero tells her that her days in the royal palace are quite boring : waking-up, eating and training, she reassures Miharu that the king will not force them to do anything and they won't be used as hostages as the heroes have the same authority as a pope, but the kingdom will insist monitoring them in the name of security. Satsuki asks coming in the castle was Rio's idea but Miharu denied it, saying it was her suggestion as she did not want Rio to do everything. Satsuki says she really want to have a chat with him, and Miharu suggests she could invite him. Satsuki finds it's really a good idea and she will do that right now which let Miharu astounded. Satsuki decides to retun in the audience room.

Satsuki and Miharu return as François is asking Rio if he wants to be knighted in Galarc for his services (saving Liselotte and Amande). The king, expecting the coversation be a little longer is surprised by the the return of the two girls. Satsuki requests Rio to be allowed to stay in her quaters tonight. Immediately this triggers Michel's jealousy, opposing to the idea of a unmarried man and a woman sleeping so close. Charlotte keeps in check her elder brother saying Satsuki is not his fiançee and François reminds him Miharu will be also there, admonishing his son they have no right to restrain Satsuki's movements or her friends. She recalls she agrees to become Galark's hero but not for the heavy monitoring, Michel reluctlantly complies. Satsuki takes Rio and Miharu and leaves the audience room.

In the hero's quarter, the serious talk can finally begin. Rio asks Miharu how much she told Satsuki. Almost all the essential has been talked about. Rio inquires about how Aki, Masato, and Miharu will be treated in the future, Satsuki answers the same as Miharu : they will be treated as state-guest but under monitoring in the name of security as the kingdom would like to know their whereabouts at any time. Rio asks also if she has an idea about the other heroes who were summoned, Satsuki says she has : since the anouncement of the ball Restoration, Beltrum, and curiously the secluded Constentella kingdom have confirmed their participation. Satsuki informs Rio she already know Beltrum's hero, Shigekura Rui through her connections in Japan as they both are parts of wealthy families. Rio guesses Satsuki belongs to the Sumeragi conglomerate which she confirms. By deduction as he knows already Restoration's hero, Rio states there is a high chance Constentella's hero to be Takahisa Sendou.

As the discussion pregresses smoothly, Rio inquires if Satsuki finds out about Liselotte. She is aware of something odd about her as Liselotte has recreated too many items from Earth to be a simple coincidence. Rio confirms Liselotte to be the same as him a reincarnated one. Then he asks Satsuki if she would like to meet Aki and Masato. She does but also states it will be very difficult as the security is very high in the castle. Rio answers her that will not be a problem to Satsuki's surprise, Miharu laughs and says Rio can do it.
