In Muv-Luv Alternative, Takeru restarts his journey to defeat the BETA once more, this time with the knowledge and strength he has acquired after having to unknowingly repeat the events of Unlimited a number of times.ДЄfter witnessing Marimo's death and the PTSD arc begins, Takeru returns to his previous world in order to live his normal life once more, with one of his major reasons being to see Sumika once more. In the ending, regardless of which heroine the player chooses to pursue, Takeru will write a heartfelt letter to Sumika, hoping that she will be able to reunite with him, even in the post-apocalyptic world he is in now.

He does his best to try and bare with the thought of losing her, but he still gets constant flashes of her, with him wishing that he could go back to his silly and calm days with her once more. After learning that there are no records of her existence, Takeru breaks down in a panic, desiring nothing more than to be with her again. While he initially just passes this off as her forgetting to wake him up, it soon becomes apparent that she does not exist in this new world. When Takeru first wakes up in the new world, the first thing he realizes is that Sumika is gone. The next day, the two of them go out to see a movie, and, afterwards, they stand together and kiss on Hakuryou Hill, vowing to always be together, with Takeru promising to marry Sumika. The two then have sex, professing their love for each other while doing so. After Tsukiyomi leaves the two of them together, they embrace each other, and Takeru takes Sumika back to his house. If Sumika has the most points, her and Takeru reach the climax of their relationship. Even if Meiya is the one who has more affection points for, he still shows regret to Sumika for abandoning her, although she assures him that she'll be happy as long as he is happy.

Takeru is confused by this, but he eventually realized that this was her way of confessing to her.ДЄfter the hot springs vacation, Takeru is given a choice of picking between Sumika and Meiya depending on who the player has gotten more affection points for. In there, she asks for him to see her not only as his childhood friend, but also as a woman. Later on, Sumika joins Takeru in the hot springs. During her conversation with Meiya, they both admit to loving Takeru, which makes him flustered. She begins to make Takeru more and more extravegant meals in order to gain more of Takeru's affection.Дuring the hot springs vacation, which is shown if the player doesn't trigger any other route flags, Sumika opens up more to Takeru, along with talking to Meiya about their mutual feelings for him. While she partially took it out on Takeru, due to her tsundere nature (to Takeru at least, she's nice to everyone else for the most part), it is evident that she is jealous of Meiya. Upon Meiya declaring that she would marry Takeru, Sumika had become very mad. All of this changed whenever a mysterious woman by the name of Meiya MitsurugiВ appeared in Takeru's bed one morning. The two continued to live a fairly normal life together, with Takeru playing video games and Sumika waking him up every day. Despite how it would seem to just be something put together to get Sumika to stop crying, she valued it deeply, and carried it around with her at almost all times. She came crying to Takeru about it, and he quickly improvised, giving her a Santa Rabbit. It is shown in a flashback that when they were young, Santa hadn't visited Sumika one year. Sumika is unable to imagine life without him. They've lived next to each other for their entire lives.
