Natsushiro Takaaki (夏代孝明, Takaaki Natsushiro), formerly known as Yuei (ゆーえい) and P-ch!, is a singer-songwriter and utaite known for his exceptionally powerful, slightly rough but solid voice, and emotional and expressive singing style. Despite this, he is not a "hot-blooded" singer in the usual sense; his voice is usually described as conveying a feeling of "intensity" rather than "fire". He is noted to have a good vocal range as well as a fair amount of technical skill, and is capable of effortlessly holding notes in addition to having a firm grasp of pitch and tone.
Although in recent months he has become well known as "Natsushiro Takaaki", he has been known by several other utaite names during his tenure on Nico Nico Douga - in fact, he uploaded his first cover in 2008 at the age of 16, under the name P-ch!. However, he first rose to prominence under the name Yuei, with relatively popular covers of "Hello/How Are You" and "Calc."; while his most popular covers under his current name include "Kimi no Oto" and "Sarishinohara".
He is noticeably close to 4Yen, Ollie, Nigauri, Kapo and Ichinose Hidenori, the first four of whom he is friends with in real life. nqrse is one of his closed friends too, since they often goes to karaoke box together and sings with each other in recently tours. He is also good friends with the producer HeavenzP, who often mixes his covers. Outside of Nico Nico Douga, he is one of the lead singers for the Japanese indie band einie (in addition to composing and writing lyrics for many of their songs) under the mononym natsushiro, along with vocalist and fellow utaite Eve.
He has stated that his real name is almost identical to his utaite name, with his real name also being "Natsushiro Takaaki" when pronounced or written in romaji; however, they are not exactly the same, as he uses a different kanji reading of "Natsushiro" in real life.
He was born in Shiga Prefecture, and currently lives in Kyoto.
He is 178 cm tall (5'10"), and weighs 54 kg (119 lb).
He is often identified with the numbers 7240 or 7246; in Japanese, if each individual digit in those numbers is expressed phonetically and then contracted, they become similar to "Natsushiro" in pronounciation: nana tsu (two) shi zero and nana tsushiroku, respectively.
His trademark favorite foods are Snickers chocolate bars; he often tweets pictures of the aforementioned confection, and is occasionally depicted in fanart with a Snickers bar.
