Tomoki once thought quite fondly of his sister and looked up to her quite affectionately. He considered her to be a very kind and caring person as she had helped him when he was in need and for playing with him.
A great example of their bond was during each of their less recent summers as they would often go out to catch cicadas together in an attempt to make money for each other by selling their husks. They built up a collection from which eventually ended up being conserved within a box for years to follow as drifted memories of the past. He even ended up writing a piece around that time of why he loved his sister so much and listed the above reasons as support.
As the siblings both grew older, Tomoki had a more than gradual turning point from where he became all around colder in attitude toward her. .
Despite this, he cares deeply for her well being and demonstrates this by being there for her in her worst moments or at least pretending not to be aware of what may have been said or happened as to lighten the emotional impact.
Examples of this can be noticed during the first episode (Chapter 004), when he pretends to not notice her while his friends persist, and then later that night finds her on a swing set and asks to walk her home.
However, there are two sides to this. If she is experiencing what he would deem an actual problem, then he will help or at least be there. But if she begins acting too strange, or if it was a self drawn situation than he will discard her call for help usually by ignoring her.
Generally, Tomoki pays little attention to Kotomi despite her crush on him. In the manga, he first meets the middle school aged Kotomi when Tomoko misinterprets her desire to give him a gift as an introduction by saying Kotomi wants his "cock". It seems Kotomi retreats into embarrassed silence until she reaches high school.
In high school, Tomoki continues to appear oblivious to Kotomi. In Chapter 108, Tomoki approaches Tomoko to ask about Kotomi. Tomoko naturally replies that she is "a raging pervert.". Later, when Tomoki sees Kotomi and Akari talking together, he approaches Akari alone to ask what type of person Kotomi is. Despite Akari wanting to remove Kotomi as a romantic rival, she instead decides to be honest and says that Kotomi is, "a very pure person." Tomoki then sees Kotomi talking with his sister who is demanding to know why her brother was asking about her, suggesting with her questions that Kotomi attempted something lewd, and leaving Tomoki to wonder if Kotomi is "a very pure pervert."
He experiences Kotomi's jealousy in Chapter 134 when she sees him with Yoshida. In apologizing to Yoshida for overreacting, she claims she has always looked upon him as a "little brother" to his inward irritation. He further finds the conflict she starts with Yoshida irritating.
Until Chapter 133, Tomoki does not have much of a relationship with or even know Yoshida. He first sees Yoshida dragging his sister to meet Megumi Imae, he wonders if Tomoko is being bullied. Yoshida notices him looking at her and demands to know what he is looking at. He inwardly concludes that she is a delinquent. He later sees her smiling while looking at pictures of an amusement park that WataMote Wiki stresses is not, in anyway, based on Tokyo Disney. He finds this strange, and Yoshida smiles at him and playfully recalls him as the "punk" she met. In Chapter 133 the two are surprised to find themselves sharing the same water dispenser in the cafeteria. Yoshida once again playfully calls him a "kid" and he cleverly replies. She then puts her arm around his shoulder and asks his name. This earns the jealous rage of Kotomi. In the process of their conflict, she learns his name, and she gives him the nickname "Tomo," while claiming that he can call her whatever he wants. She gives him her first name "Masaki" and insists does not use the honorific "san." Unfortunately, when he tries to restrain her when Kotomi reignites her attack, he grabs her by her left breast. Chapter 145 reveals that other class members noticed this.
