Sekiyu is a possible friend in 1bitheart. She works as a guide at 307 Tower. As such, she is always found at the reception desk in 307 Tower on Blue Sun Street.

"A woman working as a guide at 307 Tower. Always distanced and not very emotional. But she knows that's bad, and is practically always smiling. She also has a cruel side." -Sekiyu's Friend List description

Appearance Edit

Her entire outfit is gothic lolita themed, with a blue and black color scheme. She has light blue hair with a black ribbon on top, blue eyes, a black ascot, and wears black eyepatch with a blue rose over her right eye. She also has a short top/dress with blue down the middle and 6 black buttons. She wears a blue and black checkered ribbon on her back, and in between the ruffles of her dress. She wears brownish boots, black gloves, and is always seen holding a clipboard.

Personality Edit

A woman working as a guide, who always seems distant, not reacting much. When she's working, she's completely focused on her job. While she sounds polite, her words can have mean intentions behind them. She finds it hard to express her emotions and therefore can be rather blunt.

Background Edit

As a child, she played a lot in Twilight Park with her friends Sacchan and Yuu-chan. They stayed together throughout university, but have gotten busy and recently could not meet up.

She took her current job in order to see the smiles of others.

Relationships Edit

Yoshi Nanase/Nanashi Edit

In her free time events, she asks Nanashi to help her smile better. In the end, she comes to realize that she does not necessarily need to smile in order to be happy (or please her boss).

Trivia Edit

  • Calls certain rocks "fox's gold coins" due to them looking similar to gold coins.
  • She's good at tongue twisters.
