Within the world's largest MMORPG,Japanese player Takeru builds an original skill specialized in HP capture (life steal) and rise as a top ranker. He challenged the long-awaited most difficult event "Tower in the Sky" but got transferred to another world halfway. He then became the owner of the "Tower" with a pretty administrator. While being forced into a situation where skills are unusable, he formed a party in the new world with new friends such as an elf and a fox-eared girl and charge to a different world battle.

A fast paced refreshing story that has a sense of playing RPG.
