NTR Heroine Pure White Justice White Snow

Hayato (the protagonist), born in a village on the border of the Kingdom of North Aura, lived a peaceful life with his childhood friend Leia (the heroine).
However, the peaceful life of the village was threatened by an invasion from a neighboring country.
In order to save the village from this crisis, Hayato and Leia decided to join the Royal Knights, but…
Set in the Kingdom of North Aura, with its strict class system, this is a classic childhood friend cuckold RPG in which your beloved girlfriend is taken away by another man!

Mina Otokura is a cute girl with a boyfriend.
One day she fuses with a light fairy named Navi and turns into the heroine of justice, Crystal Mina.
Her enemy: the Three Chaos Musketeers.

But in order to fight, she needs life energy; in other words, semen, and not from her boyfriend...

In a class-based society like the North Aura Kingdom, a lowborn Hayato must rise to protect his village. Alongside his childhood friend Leia, he trains to become a Holy Knight—but other men’s desires threaten her purity.
 
Will you be able to achieve your goal and protect Leia? Or will you let someone else win her over? It is up to you to decide what fate awaits them at the end of their intense story in this NTR RPG.
 
Play as Hayato on his dangerous journey to become a Holy Knight.
 
Blast through enemies with the simple and easy turn based RPG combat system. Progress through the story quickly without the need to level up or thinking about managing your inventory. Gather clues throughout the capital to reach your desired happy ending with Leia, and protect her from being corrupted throughout your journey, or risk seeing her taken into another man's arms.
 
Gather your wits, trust your intuition, and choose the best choice to protect her... or you might lose her forever. Discover her hidden side by peeking through her memories and heart.

First time here. I was looking for the original White Album game (released in 1998 if I'm correct), but I couldn't find it anywhere. I realize it's probably not translated to English, but any and all sites I've found only link to translated versions of games. I do know some Japanese, so if anyone can point me to the Japanese version (or somewhere I can look for it), I'd be very grateful

A gruesome murder has occurred in the mansion, leaving only two witnesses. The killer is skilled at concealing their appearance, leaving the Sheriff with virtually no useful information. He’ll have to solve this mystery on his own, using his wits and the clues scattered throughout the location.
Along the way, fate will lead the Sheriff to various places, each adding more arguments to the case. Furthermore, everyone has their own opinion about what happened.
The Sheriff doesn’t care about any of it. He’s not interested in this investigation. But a little bonus, in the form of a large sum of money, compels him to take action. Of course, the girls will never leave him in peace.
