Although not much is known about Ren yet, it can be deduced that he is usually mellow and wishes for peace and quiet, much like Blake Belladonna. All in all, he seems very much in control of himself, as shown by his calm and deliberate response to the appearance of the black half of a King Taijitu. He also doesn't appear to be a morning person, as seen from his groan from having to get out of bed to get ready for the Beacon Academy Initiation.
He seems to be indifferent to Nora Valkyrie's bubbly and contrasting personality, showing a great deal of patience when dealing with his hyperactive, happy-go-lucky childhood friend. Nora has called him "the perfect student", implying that he may be something of an intellectual. However, this is not to say that he is completely humorless. He appears to be slightly playful after finding Nora in the Emerald Forest, during the events of "The Emerald Forest". Ren is also indicated to be a bit of a cook, as he makes pancakes for the team in "Forever Fall, Pt.2" and in "Search and Destroy" when Nora implied that it was his fault that she was hungry. However, not everything he cooks is well received, as the nutrition drink he prepared in "Destiny" made Nora ill.
Ren is also shown to be quite studious, as seen in "Welcome to Beacon", in which he openly agrees with Neptune Vasilias as to how libraries should be only for reading.About Me
Lie Ren is a male teenager with long black hair tied into a ponytail that ends midway down his back. There is a magenta streak on the left side of his hair. His eyes match the streak in his hair, and his clothing appears to be influenced by Chinese culture.
He wears a dark green, diagonally-buttoned, long-sleeved tailcoat that is red on the inside, with black and gold trimming and pink cuffs. The trimming goes down the right side of his torso and forms a black collar.
This color scheme seems to be influenced to some degree by the lotus flower. He wears a black, long-sleeved shirt beneath the suit, and light-tan pants with black shoes.
After the timeskip following the Fall of Beacon, his new design is updated. Ren wears his hair down and it has grown to hip-length. His attire is similar to before in color. He has a longer, sleeveless tailcoat. Under it he wears a black, sleeveless turtleneck with red, tasseled ropes over the hips, shorter pants, and calf-high open-toed sandals. From his middle finger to his biceps run gradient pink-to-black detached sleeves ending in metal armbands.
