Go to Campione copy the god killer abilities, you could also go to DxD and get longinus or even Mondaiji and copy gifts there with the different OP "Another Cosmology" like Avesta, Tai Su or Brahman. He could even copy the ability of the Wind of Decadence or The Closed Off World.

Solo Leveling should also a good world to grind Akikan. Aside from literal archangels and Monarchs who roamed the world that he could copy. There are also a lot of woman to bang.

The ability of the MC of Isekai farming anime. That godly tool is OP. The guy also has never ending endurance which could be useful to Isao where he fcked left and right. Also that anime has tons of women to bang

Stockpiling is very OP but it takes time. But sadly the villain in MHA has also OP ability but he is so stupid.

According to chinese novels, it is called "Playing pig to eat the tiger". But one should always remember that if you play pig all the time then you will become pig. Face slapping is funny but at the same time it will get annoying if it is repetitive.

If i remember correctly he should be categorized as a villain now? After all that's how society works on MHA. Without a license you can't do hero stuff.

Kill la Lill?

This is much better and direct. Like we know that his power level is already broken so why waste a few chapters in a fight where he could instantly kill the enemy? The level indicator of Danmachi didn't apply to him. He could kill the last boss of Danmachi instantly.

cant=can* sorry typo
