Mamono Realm Bento is a food described in detail in Monster Girl Encyclopedia World Guide - Side II book.
Book Entry
In the courtyard of Castle Salvarision, you can sometimes see the Dark Knights and their husbands eating their "Mamono Realm Bento" together, seated side by side. Yes, that bento contains a meal that the hubby has lovingly prepared for his knight wife as she heads off to the battlefield. But many spouses also simply eat it together. Although it is more accurate to say that it is not uncommon for the monster couple not to eat it, and the dark knight "lets" her lover eat her bento while she is busy with something more necessary... like the rabbits over there, in the corner, doing something more enjoyable. In particular, some male Knights always bring this lunch box to their spouse to shake it on her in ecstasy during the meal.
The contents of the bento are very varied and can include any possible food that can be purchased in Lescatie. Each man can choose the dishes that most please his beloved. At Castle Salvarision, the Dark Knights and their husbands eat Mamono Realm Bento together in the dining room or in the castle courtyard, but the original dish was made so that the Dark Knights could eat it during expeditions away from Lescatie.
In the past in the Kingdom of Lescatie, the food that was intended for soldiers was simple and easy to carry, being intended simply to feed the soldiers during an expedition. But in today's Lescatie, the Dark Knights must travel to human lands, "outside the mamono realm," during an expedition, so food can have a significant impact on their mission. As you know, the mamono realm of Lescatie, where the Dark Knights usually spend their time, is a Dark Mamono Realm, whose atmosphere is filled with more mamono mana than many other monster realms in the rest of the world. Of course, this mamono mana-filled environment is dangerous to humans and carries the threat of monsterization, even if one stays in it only for a short time. Therefore, when fighting against the forces of the Order that have invaded Lescatie, the Dark Knights are always in a good position to fight "defensive battles." One could say that the Mamono Realm around them is the perfect environment, which keeps their country in perfect condition.
However, as a consequence, when the Dark Knights leave Lescatie for "faraway lands," in addition to the emotional pain of having to leave their beloved spouse, they are just as affected by finding themselves in an environment different from the Dark Mamono Realm to which they are accustomed... these mamonos will be forced to operate in a place where there is virtually no mamono mana around, consequently the strength and speed they can manifest only through mamono mana will be significantly limited. During invasions, an army of Dark Knights, which from a human perspective looks like a terrifying threat, is subjected to considerable strain both physically and mentally.
In such a situation, the Mamono Realm Bento, which allows you to feel the love of your spouse, who is so far away from you, through food, is vital for married Dark Knights. In addition, by ingesting familiar foods from Mamono Realm Lescatie they activate the mamono mana in their body and raise their body condition to a level similar to what they have when they are at in the mamono realm.
Thus, the food used to fill the Mamono Realm Bento often contains a lot of monster mana and, despite its cute and appetizing appearance, can be "corrupting poison" to ordinary people.
[Mamono Realm Bento Container]
This is a polished vessel made of Mamono Realm Ore! It has a magical effect that protects the contents, and the food inside it will never lose its shape, even if you have to engage in battle! In fact, these bento containers are sold in the castle town of Salvarision as "lunch boxes that preserve the condition of the food inside" because the inside of the box is filled with mamono mana to protect the contents. Because of this, even meals made of ordinary ingredients placed inside can get the same effects as food made from mamono realm cuisine. Therefore, if a human woman uses this box as a convenient container to store her breakfast, the food inside can become mamono realm food and imperceptibly turn her into a mamono.
