Elder Tale, an MMORPG game well known across the world. After a long time since it launched, the game went viral and become one of the most famous game in the world. However, an unexpected incident occur. Thousands of players across Japan are trapped in Elder Tale, including players across the world trapped at their respective nation where their server are connected. In this new and unknown environment of Elder Tale, the players will do what they other than playing the game, but to survive and live through to find out how they trapped inside the game while trying to live through it. From here, this tales a certain young man along with the group he is part in. Despite no longer in the groups they used to be, the new group that are taking part of is much more than just a group. It is a "family." (A/N: Log Horizon is not belong to be, it is belong to the respective owner. And it is one of the favorite anime after I watch it first time before.)
