Source-derived summary

Giga (戯画) was a Japanese adult game and visual novel brand used by TGL subsidiary Entergram. The Giga brand was used on both regular visual novels as well as games that feature mecha with action-oriented gameplay elements. One of its sub-brands, Baldrhead, has been used for several of these action-oriented visual novels. Aside from their visual novels, they were known for creating the Variable Geo fighting game series for PC9800, which was later ported to TurboGrafx-CD, PC, Super Famicom, Sega Saturn and PlayStation.

Some of Giga's games have had consumer port releases onto consoles with the sexual content removed. For example, Kono Aozora ni Yakusoku o was ported to the PlayStation 2 in 2007 and the PlayStation Portable in 2009. Baldr Force was ported to the Dreamcast and PlayStation 2 and Baldr Bullet "Revellion" was ported to the PlayStation 2.

Kono Aozora ni Yakusoku o was very well received and was awarded the Bishōjo Game Award gold prize in the scenario, theme song, romance, and user approval categories in addition to the grand prize in 2006. Baldr Sky Dive1 "Lost Memories" was awarded the Moe Game Award silver prize in the theme song category in 2009.

Giga shut down and ceased selling its titles on March 31, 2023.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Giga (brand)”, the useful work is to connect “japanese video game developer” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 14, 2026.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
