Tawhid

About
Tawhid is an ADV game developed by Champion Soft and the last new title to be developed under that brand.

It's also rather unique in setting for an ADV game of it's time. Starting out in the middle east and taking you through a few other countries in the asian continent. The artstyle is also rather unique as opposed to Champion Soft and Alice Soft titles of the time.

The game's development was headed by Tori which went by Nakamura Rika for this title. Whilst not her first work as a writer (Gakeun Senki), some blogs state it's an important one for her as a scenario writer.

Gameplay
This is a menu based ADV title, for the MSX version it uses the same system as Gakuen Senki. You go around investigating various things using the presented options.

Chances are the PC-88/PC-98 version uses the same system as Little Vampire, they have a flashier intro on PC-98 at least.

Story
It's the year 2031 AD. The main character is a 28 year old ex-military photographer. He felt guilty about the ruined state of many areas after the war and thought he could at the least make sure they're remembered on film.

Whilst in Luxor, the site of the ancient capitol of Egypt, he got lost whilst going out for lunch. He met a rather strange young girl and got asked by an old man to protect her.

Follow their story as you go from ruin to ruin and evade a secret society.

Walkthrough (Japanese)
The guide is written more like a hint book. Sometimes it's direct in telling you what to do, but at other times it's just telling you an action to do which takes a lot more than what it seems.

The guide is from ymurakami, however I could not confirm it.
