Tribe: I Become Invincible With My 10,000x Bonus From The Start - Chapter 369 - How Dare They Call Themselves a War Fortress?  

Hikaru Nozomi, an ordinary university student, gets recruited by the Order of the Elements after awakening the Element of Light. And his mission? To find the other 9 Elements.

I became a scientist for an evil organization.…But I’m too competent.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…
