1st Logo (April 16, 2004-February 29, 2008)
Visuals: All of the variants of the logo consist of the company's mascot, Alice-chan, and the logo sliding from the right side of the screen. The logo consists of the text "ALICESOFT" in black with the dot of the "i" in, with two squares at the left featuring the trademark Rance character Hanny in white, with "SINCE 1989" in a bar below and the slogan "it's eroge maker!!". The versions of the logo change depending on the month or season the game is launched.

Variants:
 * Summer: Over a sparkly background, there is Alice-chan in cut-out chibi style, dressed up in a swimsuit bringing up the logo. The background then brightens up and the screen fades to white.
 * October: Over a white background, there is Alice-chan in a school gym suit carrying a flag with "1" in it. Confetti is seen moving and Alice-chan is slightly moving and blinking. The logo then slides in, settles and fades away as usual.

Technique: 2D animation in a deformed anime style.

Audio: A gentle theme, with instruments changing depending on the variant.

Availability: Seen on Rance VI, Sengoku Rance and Beat Blades Haruka.
