The supporting character's harem is very normal - Chapter 23: Contract…

The one single goal in life of the Strongest Old Sage is to subjugate the Demon King. In an epic final battle, both of them met their mutual destruction at each other’s hands.

However, the Demon King was not completely destroyed!

In order to destroy the Demon King once and for all; post-death, the Old Sage trains in the World of Gods and reincarnates as the Apostle of the Gods, Will.

In the reincarnated future, the Old Sage had become a legend and his former disciples hold the supreme authority in the world. The disciples had created an organization to oppose the Demon King and an academy to nurture the new generation of Heroes.

Thus the Apostle of the Gods, Will (8 year old), enrols into that Academy of Heroes.

This is the story of a boy on a mission to save the world through epic battles while enjoying Academy life.

Follow Kairi Izumi—a quiet, eccentric, and somewhat conspicuous girl— who never felt like anything but an NPC in a story. Working behind the scenes, unnoticed by others had always been part of her daily life, dwelling with medicine and toxins.So, it's not surprising that she wasn't tad attractive according to others.That is, until one day... that guy, he confessed to me.Wait a minute—doesn't that mean I'm a heroine now? Hang on, how is that even possible? Me? Heroine? No way! I’m just a girl from a small village who likes to help others. I don’t particularly stand out, and compared to the other girls, I’m not even that attractive.And so, a question lingers, driving the unfolding of this dumbfounding narrative forward:Wait, what do you mean I got reincarnated to be a heroine?That's weird because usually a heroine is not strong let alone smart - they are usually dumb, cute and pretty. Definitely not me. I mean, how is that possible? Me? Heroine? No way!

Sa gitna ng kabundukang binabalot ng misteryo, lumaki si Esmeralda, isang dalagang manunugis na may kakaibang lakas at talas ng pakiramdam, sa kalinga ni Ismael— isang albularyong umampon sa kanya dalawang dekada na ang nakalilipas. Ngunit sa kabila nito, nakatago ang isang katotohanang unti-unting mabubunyag— ang lihim ng kanyang pinagmulan na bumabagtas sa hangganan ng tao at mundo ng kakaibang elemento.Sa pagbabalik nila sa baryo ng kanyang lolo, harapin ni Esmeralda, hindi lamang ang sigalot sa pagitan ng kinalakhang pamilya, kun 'di pati na rin ang mga lihim ng kanyang pagkatao. Sa gitna ng pamilyar na tanawin ng baryo, magtatagpo ang landas nila ng mga taong magiging parte ng buhay niya— mayroong magiging gabay sa kaniyang pagtuklas at may iilan namang magdudulot ng kapahamakan at kalituhan sa kaniyang paghahanap ng kasagutan.Sino ba talaga siya? At ano ang pinagmulan niya?Ngunit sa bawat hakbang niya patungo sa pagtuklas ng katotohanan, lalong lalalim ang ugnayan niya sa mga anino ng mga nilalang na walang ibang nais kun 'di ang kaniyang pagkawasak. Sa bawat mutyang mahahawakan ni Esmeralda, sisigaw ang nakaraan— at sa bawat sigaw nito, unti-unting mabubuo ang kwento ng isang salinlahing nababalot ng hiwaga na siyang uukit at huhubog sa kaniyang pagkatao.

“Look at you, you were this teeny-weeny when you were little.”Using both hands, Shao Zifeng gestures how small his pet beast used to be. He then raises his head and looks at the gigantic being in front of him.“Just how did you grow into this ferocious form?”
