He found 3 sets of black keys….
[Black keys]

"...." Riku was speechless but at the same time it made sense, since this was the church and the base of you know who.
…
"And done!" Riku after eating a packet of biscuit and drinking water, he inspected his gears and found out that his Shinai and Bogu were battered. So he decided to reinforce them with anything he can find like duck tape, nails and wood.
And his efforts were rewarded with a new skill and new items.

"Let's get started then" Riku decided on a direction and set out to find more skeleton to grind.
…
3 hours later
*Bam*
"That's the last one" Riku has been killing skeletons for 3 hours and he finally finished off the last one.
"System, settle the rewards" Riku then sat on a rock and looked at the system interface with anticipation.

"Fit me to a T" Because Riku's Shinai and Bogu were broken and became useless after fighting skeletons, so he switched to the knuckle dusters.
"Am I becoming a thrill seeker or a gamber" Riku had also figured out how to increase his luck status actively. Luck can be increased actively when Riku passes a risky situation by luck or by gambling his chances. Kinda like 'plot armor'.
"Let's head back home and do some gacha" Riku exits the dungeon and returns back and starts rolling the gacha.

"I've been rolling gacha and fighting since I got here" Riku thought to himself, what should he do next.
"hmmm…..I'm gonna explore this world a little bit" Riku decided on his next action and went outside his house to explore the kuoh town.
"The main thing they show about dxd was ecchi and harem but the lore behind dxd can be explored more" Riku was lost in his thoughts as he visited various places in kuoh town.
"For now I will stay in the dark and do some planning" Riku after exploring the town returned to his house.
…
"Smells so good!" Riku after returning home cock himself a dinner consisting of fried rice, egg and spam meat.
"Itadakimasu!" Riku quickly ate all the dishes and drank some Cold tea.
