Like Toaru ossan no VRMMO with an effeminate and childish art-style. Like it the author belittles very useful skill trees that are actually very popular in any game just to make the MC look cool because he can make use of "trash" skills trees when they are actually perfectly viable. Not to mention in any decent game, all skills are useful since game balancing is a big deal in any mmo. That actually makes the author look like a noob, it would make more sense to belittle the particular combination of the chosen senses (skill trees) rather than the skills trees themselves, still with 10 different trees the player can choose that would be hard at start plus 10 or more after and the ability to change any sense whenever you want with no penalty. I can only say that the game system is very badly thought out. Not only does this make the whole premise of the MC skills being bad obsolete it also rises the question of why most characters don't change senses, those for fighting and those for town use for example since any skill like cooking, fishing or whatever can be used with no other penalty other than it not being time efficient. I find this utterly ridiculous for a game setting.
As Toaru ossan there is nothing really happening and no plot whatsoever, just menial crap and lots of explanation I don't really care about at all, also characters suck, for the most part, mainly the MC is the goody wuss type.
And last, If the developers have the tech to make 2 hour in real life feel a week in gamelife, it's utterly stupid they only use for an event, that would be something that would actually give people reason to play this game instead of others since the game itself is not good at all.
