Jun's first known band was Se'lavy. Not much is known about them except that Iori was also in the group. His second band Mar'derayla formed in 2002 and were signed to Under Code Production, a sublabel of Free-Will run by Jun's future bandmate Kisaki. The group also contained Iori on guitar, Hayato on vocals, Hagane on bass and Rui on drums. Their debut mini-album Kiseki... Ring was released in May 2003, Rui left soon after and was replaced by Toki in June. They announced they would be disbanding after the release of "Love & Peace & Horror" on March 10, 2004, but officially disbanded on August 1.
Jun (じゅん, ジュン, 준) is a very common Japanese or Korean given name used by either sex.

The name can also be written in hiragana or katakana.
In musical terminology, tempo [ˈtɛmpo] ("time" in Italian; plural: tempi [ˈtɛmpi]) is the speed or pace of a given piece or subsection thereof.
A piece of music's tempo is typically written at the start of the score, and in modern Western music is usually indicated in beats per minute (BPM). This means that a particular note value (for example, a quarter note, or crotchet) is specified as the beat, and that the amount of time between successive beats is a specified fraction of a minute. The greater the number of beats per minute, the smaller the amount of time between successive beats, and thus faster a piece must be played. For example, a tempo of 60 beats per minute signifies one beat per second, while a tempo of 120 beats per minute is twice as rapid, signifying one beat every 0.5 seconds. Mathematical tempo markings of this kind became increasingly popular during the first half of the 19th century, after the metronome had been invented by Johann Nepomuk Maelzel, although early metronomes were somewhat inconsistent. Beethoven was one of the first composers to use the metronome; in the 1810s he published metronomic indications for the eight symphonies he had composed up to that time. for example a minum has a 2 seconds
Presto was the layout engine of the Opera web browser for a decade. It was released on 28 January 2003 in Opera 7, and later used to power the Opera Mini and Opera Mobile browsers. As of Opera 15, the desktop browser uses a Chromium backend, replacing Presto with the Blink layout engine.
Presto is a dynamic engine. Webpages can be re-rendered completely or partially in response to DOM events. Its releases saw a number of bug fixes and optimizations to improve the speed of the ECMAScript (JavaScript) engine. It is proprietary software only available as a part of the Opera browsers.
A succession of ECMAScript engines have been used with Opera. (For the origin of their names, see Cultural notes below). Pre-Presto versions of Opera used the Linear A engine. Opera versions based on the Core fork of Presto, Opera 7.0 through 9.27, used the Linear B engine. The Futhark engine is used in some versions on the Core 2 fork of Presto, namely Opera 9.5 to Opera 10.10. When released it was the fastest engine around, but in 2008 a new generation of ECMAScript engines from Google (V8), Mozilla (TraceMonkey), and Apple (SquirrelFish) took one more step, introducing native code generation. This opened up for potential heavy computations on the client side and Futhark, though still fast and efficient, was unable to keep up.
