Dxd Issei : The Gaming Gear

ROMANCE

REINCARNATION

SYSTEM

The story is pretty good, but too much BS setting, especially about the level and the world setting.
1. Level. Mc only level up to lv.10 after he cleared 3 dungeon and somehow motohama, a normal human is at lv.6 and MC mom is lv.10 without doing anything.
The other chara lv are around lv.40 and Draigh is lv500. Just how much Exp mc need to gather to reach that lv.
2. Dungeon. The problem about the dungeon is they have an OP barrier/cell even though it just a low lv dungeon. The rat only at lv10, but they have a barrier that not only couldn't be destroyed by koneko and akeno, the barrier able to neutralize Kiba sacred gear and immune to Rias Power of Destruction.
It just too much BS and the impact to the world just too much considering in the OG only Rezivim as the last boss that able to neutralize a sacred gear and no one immune to POD.
3. Slow pace, mc just grinding in the dungeon from the start until ch30. No other plot happens in 30ch. I know that too fast pace OP Mc is boring but only grinding for 30ch and only reach lv.10 after all of that battle is bs. Slow, boring and weak.
4. Unnecessary enemy. Author create new Sacred gear for Mc just to use the same setting of the Og HeavenlyDragon. Now issei not only have to fight Vali, he need to fight other user of gamer gear and an unknown weird Organizations. 

this theme is very good, there are very few currently but I think it's very cool that the heroines listen to the protagonist's thoughts, the development of the story is going very well too, I'm enjoying the decision making of each character.

I'll give it a five star for now because i like the concept and the staring chapter.

It’s gonna go so far the character development is very great. The background characters too I like it.

se veía interesante hasta que me di cuenta de que hay otra persona con un gamer gear, la cual es literalmente un enemigo completamente innecesario.
