Current

Despite being the youngest of the three siblings, T-shi always tries to be a reliable person and often helps with house chores. Thanks to his easy-going and friendly nature, he gains popularity in the neighborhood, along with girls and boys alike in his school. As much as T-shi tries, however, sometimes he lets it slip and does something appropriate for his age, such as being weirdly competitive on the smallest things.

His grades in school isn't the best one, yet he make it up by being the top on sports in his grade. He is also a member of the Track and Field club. T-shi is pretty proud of his speed, as his friends often ask him to play ball games and not many can match him.

Actually T-shi gets easily anxious when being alone, so he tries to make friends with everyone in the neighborhood. He is also not good at hiding his emotions, as everything he thinks or feels are shown as clear as day in his face.

Past

Back when he was six years old, a small incident happened. At that time, he was looking after the home with his oldest brother, who later on left T-shi alone for a motorcycle drive without notifying him.

The problem happens when T-shi finished using the bathroom and as ill luck would have it, the door was jammed. Being trapped inside and with no means to contact for help, T-shi panicked and tried to kick down the door but it didn't do much. He then started to shout for help, yet there was no response as the house was empty at that time. For a long time, T-shi was helpless and couldn’t do anything but stay still.

Later in the evening, the second oldest brother got home; hearing sobbing sounds from the bathroom, he rushed and was shocked to find his younger brother there—looking disheveled and terrified. Relieved to be out of the cramped space after who knows how many hours, T-shi cried out on his brother—so much that he got a fever afterwards. Since that day, T-shi greatly feels uneasy to be in closed spaces.

Family

T-shi lives with his family in the countryside. He is the youngest of three brothers and his family consists of his father, mother, and two older brothers with a pretty significant age gap. Both of his parents work on a family farm, and T-shi often helps them out with fieldwork, which made T-shi naturally good at waking up in the mornings.

His oldest brother by ten years is a carefree person, while his second oldest brother by seven years is a worrywart person and currently studying outside in the city. T-shi will happily talk about his admiration towards his second oldest brother, while he quickly get silent when talking about the oldest one. T-shi addresses both of his brothers by "Nii-san".
