This is a style LoRA based on Takeda Yuichi (who went by the name Takenouchi Yusuke as the character designer for VN). I’ve always liked his bold and well-defined characters, typical of the 1980-1990s. Sadly, he passed away in 2005.
Add "1980s (style), retro artstyle" or "1990s (style), retro artstyle" if you like.
