RIP constructor, you will be missed for your great games. I played this series for countless hours back then and don't regret my investments. (Pun possibly intended.)
Sprites should not be tagged, but all characters appearing in sex scenes (everyone except the PC - Takamine) and passing presence can per the wiki rules, so they have been tagged. Otoha Jousaki was used as there are no remnants of official furigana/yomigana for Otoha's last name and Syo is not a proper onyomi for 城 on top of not being valid Hepburn romanization (unless it was intended by the scenarist and written that way in actual Roman alphabet).
Review: Leavel Estate (Reavel Estate) is highly recommended to all Itadaki Street/Monopoly and board game fans in general. Skills allow for quite a lot of luck removal and are pretty challenging, if not overpowered for some characters. The downside is none of the female characters are playable and the games do not have a multiplayer feature. Takamine can still get access to all of their passive skills for those who know not to rely on skills for the entire game and have enough patience.
Edited the description to make Syosaki > Jousaki per AgentLillian's comment. I hardly know Japanese and I can't remember if I found these names written down or if I just tried to romanize on my own. It's been a while, but the games were great fun. I stumbled upon these by accident when playing their earlier yakyuuken games, which I'll also heartily recommend.
