Riot Grasper

Riot Grasper summary:

Agatsuma Seiji accidentally dies in his current world. Due to a certain reason, he chooses a world other than Earth as the destination for his reincarnation. Incidentally, he receives a special skill upon his reincarnation, Thief’s G.o.dly Skill (Riot Grasper), the attraction of which is the ability to steal skills from others.
How will a boy, who longs for nothing but ‘cool’, live his life in this otherworld with the Thief’s G.o.dly Skill!?
“Well… aren’t ordinary people boring?
No! I firmly refuse!
For me! For my sake——
I can’t run away from this place!!”
Will Seiji make full use of his skill and plunder others, or will he play by the rules——!?
